Description

These data contain raw and processed hourly observations from a stationary Hydroinnova cosmic ray neutron sensor (CRNS). Data were collected between 22 November 2020 and 08 May 2021 at the SnowEx Prairie site at the Central Agricultural Research Center (CARC) in Moccasin, Montana and represent a footprint area of approximately 171 meters radius around the instrument. Observations in the raw files include neutron counts, atmospheric pressure, temperature, and relative humidity and related correction factors. These observations were converted to snow water equivalent (SWE) and soil moisture in the processed data files using Desilets, 2017, methodology from Schrön et al., 2017, and in-situ soil moisture samples collected on 06 May 2021 (available as <a href="https://nsidc.org/data/snex21_dsm/versions/1">SnowEx21 Prairie Station in Situ Dielectric Soil Moisture and Soil Temperature, Version 1</a>).
