ABoVE: Active Layer Thickness Derived from Airborne L- and P-band SAR, Alaska, 2017

This dataset provides estimates of seasonal subsidence, active layer thickness (ALT), the vertical soil moisture profile, and uncertainties at a 30 m resolution for 28 sites across the ABoVE domain, including 16 sites in Alaska and 12 sites in Northwest Canada. The ALT and soil moisture profile retrievals simultaneously use L- and P-band synthetic aperture radar (SAR) data acquired by the NASA/JPL Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) instruments during the 2017 Arctic Boreal Vulnerability Experiment (ABoVE) airborne campaign.

本数据集提供了ABoVE区域28个站点（包括阿拉斯加的16个站点和加拿大西北部的12个站点）的季相沉降、活动层厚度（ALT）、垂直土壤水分剖面及其不确定性估计，分辨率为30米。活动层厚度和土壤水分剖面的提取同时利用了NASA/JPL无人驾驶航空器合成孔径雷达（UAVSAR）仪器在2017年北极 boreal易损性实验（ABoVE）空中任务期间获取的L波段和P波段合成孔径雷达（SAR）数据。
