Abstract:

SNOTEL, which stands for Snowpack Telemetry, is an automated system designed to collect snowpack and related climatic data in the Western United States.

The basic SNOTEL station provides snowpack water content data via a pressure-sensing snow pillow. It also collects data on snow depth, all-season precipitation accumulation, and air temperature with daily maximums, minimums, and averages. Many of the enhanced SNOTEL stations are also equipped to take soil moisture and temperature measurements at various
depths.

The stations in this data set were downloaded from the National Water and Climate Center web site at http://www.wcc.nrcs.usda.gov/nwcc/inventory. Geographic coordinates of stations available from this web site are rounded to the nearest 0.01 degrees of latitude (approximately 1000 meters) for security purposes.

Purpose:

This data set provides approximate locations of SNOTEL stations to facilitate understanding and mapping of their spatial distributon.

Data from the SNOTEL network allow agencies to develop accurate and reliable water supply forecasts, climate studies, air and water quality investigations, climate change, and endangered species habitat analysis.
