Active Layer Thickness Derived from Airborne L- and P-band SAR

Sites in Version 2 of the Permafrost Dynamics Observatory Project product.

Sites in Version 2 of the Permafrost Dynamics Observatory Project product. Green = data delivered in Version 2. Red = not delivered in Version 2 but will be delivered in future version. Yellow = not processed due to only L-band data being available.

Estimates of seasonal subsidence, ALT, vertical soil moisture profile, and uncertainties at a 30-m resolution for 28 sites across the ABoVE domain are now available.
