Sawtooth Range Weather Station

A year-around weather station was installed at the Sawtooth Range site in May of 1998. The primarly purposes are:  a) to measure the atmospheric energy available for snowmelt, b) to determine the strength of association between energy input, and both streamflow and sediment transfer, and c) to ascertain the extent to which AES weather station Eureka observations adequately represent the climate of the basin.

Summer 1998

The sediment coring team recovered data from the station in May of 1999. During a subsequent visit in June of 2000 (Ted Lewis & Pierre Francus), a nipher-shielded precipitation gage was added to the station, in anticipation of a comprehensive field season at the lake in 2001. We are now collecting a third year of data from the site.

Measurement and control of the weather station use a DC and solar powered datalogger, similar to automated weather stations (AWS) that we have operated elsewhere [other UMass AWS]. Data are being stored at the station electronically, by two different devices for security purposes. The array of sensors at the station include those to measure:  barometric pressure, wind speed & direction, temperature & humidity, and snow accumulation/ablation.
