ABoVE: Active Layer and Soil Moisture Properties from AirMOSS P-band SAR in Alaska
This dataset from the Arctic-Boreal Vulnerability Experiment (ABoVE) provides estimates of soil geophysical properties derived from Airborne Microwave Observatory of Subcanopy and Subsurface (AirMOSS) P-band polarimetric synthetic aperture radar (PolSAR) data collected in August and October of 2014, 2015, and 2017 over 12 flight transects across Northern Alaska. Soil properties reported include the active layer thickness (ALT), dielectric constant, soil moisture profile, surface roughness, and their respective uncertainty estimates at 30 m spatial resolution over each transect. Soil moisture profiles and ALT are key variables in understanding the permafrost active layer dynamics that respond to the summer climate and land surface conditions.
ABoVE is a NASA Terrestrial Ecology Program field campaign in Alaska and western Canada between 2016 and 2021. See all ORNL DAAC datasets from ABoVE.
