Here is my weekly weather quiz question for the last time “What is “Snotel?” Here is the correct answer. SnotelSNOw TELemetry – is an automated network of snowpack data collection sites. The Natural Resources Conservation Service (NRCS), formerly the Soil Conservation Service (SCS), has operated the Federal-State-Private Cooperative Snow Survey Program in the western United States since 1935. A standard SNOTEL site consists of a snow pillow, a storage type precipitation gauge, air temperature sensor and a small shelter for housing electronics.
