Hourly Soil Moisture Logger Data from Alaska and Alberta

Hourly in-situ soil moisture measurements from data loggers in organic soils at two locations: along the Sag River in Alaska and near Red Earth Creek in Alberta. The dataset includes soil moisture probe periods, temperature readings, and calibration coefficients for deriving volumetric moisture content. Provided by NASA, the data spans from July 2017 to July 2021 with some interruptions.

Use Cases

• Calibrating satellite soil moisture algorithms using in-situ probe measurements and derived volumetric moisture content.
• Analyzing soil moisture and temperature time series in organic, low-density soils.
• Validating hydrological models with field measurements from distinct Arctic and boreal locations.
• Studying soil profile characteristics using provided calibration coefficients and soil profile measurements.

Strengths

• Data includes calibration coefficients and soil profile measurements for per-probe calibrations.
• Covers a multi-year time range from July 2017 to July 2021.
• Measurements are from two distinct geographic locations in Alaska and Alberta.

Limitations

• Exact row count, file size, and specific column names are not provided by any source.
• Data collection had interruptions, as noted across all sources.
• License is ambiguously listed as 'other-license-specified' on Data.gov, with no license on NASA Earthdata.
