1.3 SITING AND EXPOSURE

CAUTION: If any part of the weather station comes in contact with power lines, you could be killed. Contact local utilities for the location of buried utility lines before digging or driving ground rods.

Selecting an appropriate site for the weather station is critical in order to obtain accurate meteorological data. In general, the site should be representative of the general area of interest, and away from the influence of obstructions such as buildings and trees.

The weather station should not be located where sprinkler irrigation water will strike sensors or instrument enclosure.

Some general guidelines for site selection are listed below, which were condensed from EPA

(1988)

1

, WMO (1983)

2

, and AASC (1985)

3 publications.

1.3.1 WIND SPEED AND DIRECTION

Wind sensors should be located over open level terrain, and at a distance of at least ten times

(EPA) the height of any nearby building, tree or other obstruction, as illustrated in Figure 1.3-1.

Standard measurement heights:

3.0 m ± 0.1 m recommended (AASC)

2.0 m ± 0.1 m, 10.0 m ± 0.5 m optional (AASC)

10.0 m (WMO and EPA)

1.3.2 TEMPERATURE AND RELATIVE

HUMIDITY

Sensors should be located over an open level area at least 9 m (EPA) in diameter. The surface should be covered by short grass, or where grass does not grow, the natural earth surface. Sensors should be located at a distance of at least four times the height of any nearby obstruction and at least 30 m (EPA) from large paved areas. Sensors should be protected from thermal radiation, and adequately ventilated.

Situations to avoid include:

• large industrial heat sources

• rooftops

• steep slopes

• sheltered hollows

• high vegetation

• shaded areas

• swamps

• areas where snow drifts occur

• low places holding standing water after rains

Standard measurement heights:

1.5 m ± 1.0 m (AASC)

1.25 - 2.0 m (WMO)

2.0 m temperature (EPA)

2.0 m and 10.0 m for temperature difference

(EPA)

1.3.3 PRECIPITATION

A rain gage should be sited on level ground that is covered with short grass or gravel. In open areas, the distance to obstructions should be two to four times (EPA, AASC) the height of the obstruction.

The height of the opening should be as low as possible, but should be high enough to avoid splashing from the ground. Wind shields, such as those used by the National Weather Service, are recommended for open areas.

1-3

SECTION 1. PREPARATION AND SITING

Collectors should be heated, if necessary, to properly measure frozen precipitation. The gage must be mounted above the average level of snow accumulation in areas that experience significant snowfall.

Standard measurement heights:

1.0 m ± 1.0 cm (AASC)

30.0 cm minimum (WMO, EPA)

1.3.4 SOLAR RADIATION

Pyranometers should be located to avoid shadows on the sensor at any time. Mounting it on the southern most (northern hemisphere) portion of the weather station will minimize the chance of shading from other weather station structures. Reflective surfaces and sources of artificial radiation should be avoided. The height at which the sensor is mounted is not critical.

1.3.5 SOIL TEMPERATURE

The measurement site for soil temperature should be at least 1 m

2 and typical of the surface of interest. The ground surface should be level with respect to the immediate area (10 m radius).

Standard measurement depths:

10.0 cm ± 1.0 cm (AASC)

5.0 cm, 10.0 cm, 50.0 cm, 100.0 cm (WMO)

SECTION 1. PREPARATION AND SITING

1.4 DETERMINING TRUE NORTH FOR

WIND VANE ORIENTATION

Magnetic declination, or other methods to find True

North, should be determined prior to installing the weather station. True North is usually found by reading a magnetic compass and applying the correction for magnetic declination*; where magnetic declination is the number of degrees between True North and Magnetic North. Magnetic declination for a specific site can be obtained from a

USFA map, local airport, or through an internet service called NSSDC CGM (Section 1.4.1). A general map showing magnetic declination for the contiguous United States is shown in Figure 1.4-1.

Declination angles east of True North are considered negative, and are subtracted from 0 degrees to get True North as shown Figure 1.4-2.

Declination angles west of True North are considered positive, and are added to 0 degrees to get

True North as shown in Figure 1.4-3. For example, the declination for Logan, Utah is 14.5

°

East. True North is 360

°

- 14.5

°

, or 345.5

°

as read on a compass.

* Other methods employ observations using the North Star or the sun, and are discussed in the Quality Assurance

SECTION 1. PREPARATION AND SITING

1.4.1 NSSDC CGM SERVICE

The NSSDC CGM (Corrected Geomagnetic)

Service provides an easy way of determining magnetic declination of a specific site. Since magnetic declination fluctuates with time, it should be determined each time the wind vane orientation is adjusted. It can be accessed on the world wide web at http://nssdc.gsfc.nasa.gov/space/cgm/cgm.html

If you know the latitude and longitude of your site, fill out Form 1as shown below for an accurate magnetic declination. If you do not know the latitude and longitude of your site, fill out Form 2 for estimate of magnetic declination.

Note that longitude is expressed in 0 to 360 degrees east of the Greenwich prime meridian, and that north latitudes are positive.

SECTION 2. UT30 TOWER INSTALLATION

2.1 UT30 TOWER INSTALLATION

The UT30 10 meter tower provides a support structure for mounting the weather station components. Figure 2.1-1 shows a typical

UT30 equipped with instrumentation enclosure, meteorological sensors, and solar panel.

2.1.1 TOWER INSTALLATION SAFETY

CONCERNS

WARNING: Tower installation near power lines is dangerous. The minimum safe recommended distance from overhead power lines is 2 times the height of the tower and mast combined.

When installing the tower, remember:

•

DO NOT use a metal ladder

•

DO NOT work on a wet or windy day

•

DO dress properly

− shoes with rubber soles and heels, rubber gloves, and long sleeves.

2.1.2 BASE AND GUY ANCHOR LAYOUT

1. A guyed UT30 tower requires an area approximately 17 feet in diameter. Brush and tall weeds should be removed, otherwise the natural vegetation and ground surface should be disturbed as little as possible.

2. Drive a stake where the base of the tower will be located. Attach a line to the stake and scribe a circle with a 17 foot radius.

Drive a stake on the scribed line opposite the direction the tower will hinge for the first guy anchor location (Figure 2.1-2).

On level ground, lay out the remaining two anchor locations by measuring 29.5 feet from the first anchor to the scribed line on either side of the base stake (Figure 2.1-2).

On unlevel ground, use a compass at the base stake to lay out the remaining two anchor locations 120 degrees from the first.

Vary the distance between the tower and each anchor so that the angle between the tower and the guy wire will be approximately

30 degrees.

2.1.3 TOWER BASE INSTALLATION

There are two base options: the B18 base is poured in concrete; the RFM18 roof mount base is anchored to a flat surface.

2.1.3.1 B18 Base installation

1. Dig a hole 36" square and 48" deep where the tower base will be located (Figure 2.1-3).

2. Optional

 construct a concrete form out of

2" x 4" lumber 36" square (inside dimensions). Center the form over the hole and drive two stakes along the outside edge of each side. Level the form by driving nails through the stakes and into the form while holding the form level.

3. Attach the bottom section of the tower to the B18 base using one bolt per leg, making sure that the hinge direction is common for all legs.

4. Center the bottom tower section with the base attached in the hole. Orient the tower/base for the proper hinge direction.

Make sure that the top of the legs will be at least 1/2" above the finished height of the concrete (Figure 2.1-4).

5. Fill the hole with concrete. Getting the bottom tower section plumb is very important. As concrete is poured into the hole, periodically check the tower for plumb using a carpenter's level and make adjustments as necessary. Allow three to four days for the concrete to cure.

2.1.3.2 RFM18 Base Installation

1. Position the RFM18 on the surface where it will be installed. Make sure the hinge direction is correct and mark the locations of the three mounting holes. Install an appropriate anchor

(user-supplied) for each hole.

Attach the bottom section of the tower to the RFM18 base using one bolt per leg

(Figure 2.1-5). Position the base over the anchor holes. Secure the base to the anchors with appropriate hardware (usersupplied). Check the tower for plumb and shim the RFM18 if necessary before fully tightening the bolts.

2.1.4 GUY ANCHOR INSTALLATION

There are two types of anchors for the tower guy wires: the UTEYE eye bolts are poured in concrete; the UTDUK duckbill anchors are driven into the soil.

2.1.4.1 UTEYE Eyebolt Guy Anchor

1. Dig a hole 24" square by 24" deep at each anchor location (Section 2.1.2).

2. Optional

 construct a concrete form out of

2" x 4" lumber 24" square (inside dimensions) for each hole. Center the forms over the holes and level them using a carpenter's level and stakes.

3. Fill the holes with concrete and install the eyebolts as shown in Figure 2.1-6.

2.1.4.2 UTDUK Duckbill Guy Anchor

1. Locate the three anchor locations (Section

2.1.2). It is important that the anchors be driven at the same angle as the guy wires

(Figure 2.1-7). Insert the steel drive bar into the anchor body and drive the anchor into the ground using a fence post driver or sledgehammer until only the top half of the loop remains above the ground.

2. Attach a high-lift jack to the loop and jack the anchor up about 6 inches to rotate the anchor into the load-lock position.

WARNING: Failure to install and lock the anchor at the correct angle will result in the anchor cable cutting through the soil until the angles equalize, causing slack in the guy wires.

3.4 SEALING AND DESICCATING THE

ENCLOSURE

The MetData1 enclosure is supplied with desiccant packs. The desiccant maintains a low humidity in the enclosure to minimize the chance of condensation on the instrumentation. The desiccant must be changed periodically. Place one or two desiccant packs into desiccant holder just before leaving the installation site. Be sure to close the lid. A desiccant change is indicated when the internal MetData1 humidity sensor measures 30% or higher. Keep unused desiccant tightly sealed in an airtight container.

BUCKET RAIN GAGES (TE525,

TE525WS, TE525MM)

1. Mount the rain gage to a vertical pipe as shown in Figure 4.13-1. Mounting the gage directly to the tripod or tower is not recommended.

2. Dig a 6" diameter hole 24" deep.

3. Center a 1 1/4" to 2" IPS pipe in the hole and fill the hole with concrete. Use a level to plumb the pipe as the hole is filled.

4. After the concrete has cured, attach the rain gage to the top of the pipe with the hose clamps provided. Route the sensor lead to the tripod in plastic or metal conduit.

4.14 CS700-L RAIN GAGE

The CS700-L should be mounted in a relatively level spot that is representative of the surrounding area. The lip of the funnel should be horizontal and at least 30 inches above the ground. The ground surface around the rain gage should be natural vegetation or gravel.

The gage should not be installed over concrete or pavement.

1. Mount the CS700 to either the CM100

(Figure 4.14-1) or a user supplied bracket.

Remove the CS700-L funnel from the base by removing the three screws and lifting upward. Adjust the three nuts on the

CM100 bracket to level the rain gage. On user supplied brackets, shims or washers can be used to level the rain gage. A bubble level is mounted on the CS700-L base to facilitate leveling.

2. Remove the rubber shipping band and cardboard packing securing the tipping bucket assembly. Tip the bucket several times to insure the tipping mechanism is moving freely.

3. Replace the housing assembly and tighten the three screws to secure the housing to the base.

4.16 CS615 WATER CONTENT

REFLECTOMETER

Probe rods can be inserted vertically or horizontally into the soil surface, as shown in

Figure 4.16-1, or buried at any orientation to the surface. A probe inserted vertically into a soil surface will give an indication of the water content in the upper 30 cm of soil. Horizontal installation will detect the passing of wetting fronts. Insertion at a 30 degree angle with the surface will measure water content in the upper

15 cm of soil.

Probes must be inserted such that no air voids are created around the rods, and that the rods remain as parallel as possible. Use the

CS615G probe insertion guide to minimize errors due to improper insertion.

The standard calibration for the CS615 probe, as programmed in Short Cut, is valid for loamy soils with low organic content. In other types of soils, reporting the output in units of period will make it possible to apply your own calibration during post processing of data.

Mounting and orientation considerations are left to the user to determine. Consult the 237 manual for preparation and other information.

Normally, the sensor is mounted away from the meteorological tower in or near a plant canopy.

4.18 257 SOIL MOISTURE SENSOR

1. Soak the sensor end of the 257 in irrigation water for 12 to 14 hours. Allow the sensor to dry for 1 to 2 days after soaking and repeat the soak/dry cycle twice to improve sensor response. Always install a wet sensor.

2. Install the sensor into soil representative of the field conditions you wish to monitor.

Avoid high or low spots. Placement south of the weather station mast (northern hemisphere) will avoid the effects of the mast shade. Installation in the root zone is best if measurements are used for irrigation purposes.

3. The 257 should be removed from the soil prior to harvest or cultivation operations to avoid damaging the sensor or sensor cable.

Remove when soil is moist.

4.20 WIND DIRECTION SENSOR

ORIENTATION

4.20.1 DETERMINING TRUE NORTH AND

SENSOR ORIENTATION

Orientation of the wind direction sensor is done after the datalogger has been programmed, and the location of True North has been determined. True

North is usually found by reading a magnetic compass and applying the correction for magnetic declination*; where magnetic declination is the number of degrees between True North and

Magnetic North. Magnetic declination for a specific site can be obtained from a USFA map, local airport, or through a computer service offered by the USFS called GEOMAG (Section 4.20.2). A general map showing magnetic declination for the contiguous United States is shown in Figure 4.20-1.

Declination angles east of True North are considered negative, and are subtracted from 0 degrees to get True North as shown Figure 4.20-2.

Declination angles west of True North are considered positive, and are added to 0 degrees to get

True North as shown in Figure 4.20-3. For example, the declination for Logan, Utah is 16

°

East. True North is 360

°

- 16

°

, or 344

°

as read on a compass.

Orientation is most easily done with two people, one to aim and adjust the sensor, while the other observes the wind direction displayed by the datalogger.

1.

Establish a reference point on the horizon for

True North.

2.

Sighting down the instrument center line, aim the nose cone, or counterweight at True North.

Display the input location for wind direction using the *6 Mode of the datalogger, or, the

Monitor Mode of GraphTerm with an on-line

PC.

3.

Loosen the band clamps or set screws that secure the base of the sensor to the mast or crossarm. While holding the vane position, slowly rotate the sensor base until the datalogger indicates 0 degrees. Tighten the band clamps or set screws loosened previously.

4. Engage the orientation ring indexing pin in the notch at the instrument base (05103 and 05305 sensors only), and tighten the band clamp on the orientation ring.

SECTION 6. MAINTENANCE AND TROUBLESHOOTING

These guidelines apply to several different Campbell Scientific weather stations.

6.1 MAINTENANCE

Proper maintenance of weather station components is essential to obtain accurate data. Equipment must be in good operating condition, which requires a program of regular inspection and maintenance. Routine and simple maintenance can be accomplished by the person in charge of the weather station.

More difficult maintenance such as sensor calibration, sensor performance testing (i.e., bearing torque), and sensor component replacement, generally requires a skilled technician, or that the instrument be sent to

Campbell Scientific or the manufacturer.

A station log should be maintained for each weather station that includes serial numbers, dates that the site was visited, and maintenance that was performed.

6.1.1 INSTRUMENTATION MAINTENANCE

The instrumentation requires a minimum of routine maintenance. A few preventative maintenance steps will optimize battery life and decrease the chances of datalogger failure.

solar panel at all times. The charge indicating diode should be "ON" when voltage to the charging circuitry is present. Be aware of battery voltage that consistently decreases over time, which indicates a failure in the charging circuitry.

6.1.3 DESICCANT

Enclosure humidity is monitored in the ET

Enclosure and MetData1 systems by an RH chip incorporated into the connector board.

Change the desiccant packs when the enclosure RH exceeds 35%. The RH chip should be changed every 3 to 5 years.

In standard weather stations, a humidity indicator card is provided with the enclosure. A small RH sensor (10162) can be purchased separately to record the RH inside the enclosure. Change the desiccant when either the card or the sensor read about 35% RH.

Desiccant may be ordered through Campbell

Scientific (DSC 20/4).

Desiccant packs inside of the dataloggers do not require replacement under normal conditions.

6.1.2 BATTERIES

Instruction 10 can be used to measure battery voltage. By recording battery voltage the user can determine how long a fresh set of batteries will last (see the Installation Section of the datalogger Operator's Manual for cold temperature effects on alkaline batteries).

Short Cut and ETPro automatically program the weather station to measure battery voltage.

When alkaline batteries are used, the battery voltage should not be allowed to drop below 9.6

VDC before replacement. Where CR10 or 21X dataloggers are used in the instrumentation, an external battery must be used to maintain power to the datalogger when changing batteries, otherwise the clock, program, and data will be lost (refer to the Installation Section of the datalogger's Operator's Manual for details).

When not in use, remove the eight cells to eliminate potential corrosion of the contact points, and store in a cool dry place.

Rechargeable power supplies should be connected to an AC transformer or unregulated

6.1.4 SENSOR MAINTENANCE

Sensor maintenance should be performed at regular intervals, depending on the desired accuracy and the conditions of use. A suggested maintenance schedule is outlined below.

1 week

•

Check the pyranometer for level and contamination. Gently clean, if needed.

•

Visually inspect the wind sensors and radiation shield.

1 month

•

Check the rain gage funnel for debris and level.

•

Do a visual/audio inspection of the anemometer at low wind speeds.

•

Check the filter of the temperature/humidity sensor for contamination.

6.2 TROUBLESHOOTING

6.2.1 NO RESPONSE USING THE KEYPAD

Check keypad response after each of the following steps.

A.

Make sure the battery has been installed, and the power switch, if any, is "ON"

(Section 7).

B.

Use a voltmeter to measure the voltage on the 12 V and G terminals; the voltage must be between 9.6 and 16 VDC.

C. Disconnect any sensor or peripheral wires connected to the 5 V and 12 V terminals.

D. Disconnect any communications or storage peripherals from the datalogger.

E.

Reset the datalogger by turning the power switch to "OFF", then to "ON" or disconnecting and reconnecting the battery.

F.

If still no response, call Campbell Scientific.

6.2.2 NO RESPONSE FROM DATALOGGER

THROUGH SC32A OR MODEM PERIPHERAL

At the datalogger:

A.

Make sure the battery has been installed, and the power switch, if any, is "ON" (Section 7).

B.

Use a voltmeter to measure the voltage on the 12 V and G terminals; the voltage must be between 9.6 and 16 V DC.

C. Make sure the datalogger is connected to the modem, and the modem is properly configured and cabled (Section 9).

At the computer:

D. Make sure the Station File is configured correctly (PC208 Manual).

E.

Check the cable(s) between the serial port and the modem. If cables have not been purchased through Campbell Scientific, check for the following configuration using an ohm meter:
