TY - GEN T1 - Hourly Soil Moisture Logger Data, Alberta and Alaska, 2017-2021 AU - Bourgeau-Chavez, L.L. AU - Graham, J.A. AU - Bosse, K. AU - Poley, A. AU - Battaglia, M.J. AU - Hart, B. DO - 10.3334/ORNLDAAC/2123 UR - https://daac.ornl.gov/cgi-bin/dsviewer.pl?ds_id=2123 AB - This dataset includes hourly in-situ soil moisture measurements from data loggers in predominantly organic soils (very low bulk density) at two locations: 1) along the Sag River in Alaska, U.S., and 2) near Red Earth Creek in Alberta, Canada. The dataset also provides soil moisture probe periods, temperature probe readings, as well as calibration coefficients and soil profile measurements used to create per probe calibrations for derived volumetric moisture content. The Campbell Scientific CR200 data loggers used CS625 water content reflectometers and temperature probe 109. Further details to the derivation of the calibrations are provided in a supplementary document. The purpose of the dataset is to provide field measurements that can be used for calibration/validation for satellite-based soil moisture retrieval algorithms. With some interruptions, the dataset exists from July 2017 to July 2021. The data are provided in comma-separated values (CSV) format.
