---Instrument Siting---
In setting up the station, every effort was made to install the sensors
as close as
possible to their respective meteorological
standards. A summary is
as follows:
| Sensor | This station | Meteorological standard |
|---|---|---|
| Temperature/Humidity | 5 feet above ground | 5 feet above ground |
| Rain Gauge | Approx. 6 feet above ground | As low to the ground as possible while avoiding obstructions |
| Wind Vane/Anemometer | Approx. 32 feet above ground | 29.5-32.8 ft (9-10m) for ASOS/AWOS; 20 ft for RAWS stations |
| Barometer | Mounted indoors | Usually mounted indoors |
