ORNL DAAC Data Release - ABoVE: Soil Moisture and Active Layer Thickness in Alaska, USA and Canada, 2005-2022

[ORNL - blancohl]

ORNL DAAC recently released a new ABoVE dataset by Moore, M.A. et al (2025):

ABoVE: Soil Moisture and Active Layer Thickness in Alaska, USA and Canada, 2005-2022

This dataset provides soil thaw depth and moisture measurements and dielectric properties measured by different research teams at sites in Alaska, U.S., and the Northwest Territories, Canada. There are multiple observations per site and 528,703 total observations. The dataset includes 223,230 observations of active layer thickness measured by mechanical probing (9.8%) or ground penetrating radar (GPR) (90.2%). Approximately 179,154 volumetric water content (VWC) measurements were collected using GPR (2.0%), HydroSense I and II probes (8.8%), in situ loggers (89.2%), and DualEM (<1.0%). Metadata includes the ___location, time, geospatial coordinates, sampling technique, measurement teams, and field team contact information.
