- History: This station has been in existence since the
1930's. Pre 1949 this station was called Beltsville Plant Industry Station #6.
Strip charts are available for temperature, humidity
and rainfall for the period from the 1950's to 1997. Pre 1950's the records are mostly typed
forms and handwritten records (does not seem to be complete). The temperature charts
were generated using hygrothermographs
inside a standard National Weather Service instrument shelter.
The rainfall charts were generated using a Universal Rain Gage.
In 1995 a computerized
station was added at the same location.
This station
has a ten foot tower using:
- A datalogger logging data on 15 minute intervals.
- Temperature and Humidity probe in a 12-gill plate radiation
shield installed at a five foot elevation.
- Windspeed and direction installed at a ten foot elevation.
- Pyranometer installed at a ten foot elevation.
- Tipping Rain Gage mounted three foot off the ground on a
separate pole about ten feet from the main tower.
