USDA Snowpack Telemetry Network (SNOTEL)

is an automated system of snowpack and related climate sensors primarily in mountainous regions in the Western United States which aims to collect data like snow water equivalent, accumulated precipitation, and air temperature. This is a proxy of the SNOTEL API into the OGC API EDR format.
