资源简介：
<p>This Level-3 (L3) product provides a daily global composite of Northern Hemisphere landscape freeze/thaw conditions retrieved by the Soil Moisture Active Passive (SMAP) radar from 6:00 a.m. descending and 6:00 p.m. ascending half-orbit passes. Input SMAP L-band backscatter data used to derive freeze/thaw are resampled to an Earth-fixed, global cylindrical 3 km Equal-Area Scalable Earth Grid, Version 2.0 (EASE-Grid 2.0). <!--A variety of ancillary data are also used as input, such as landcover classification and open water body fraction.--> </p>
<p><strong>Note:</strong> These data are Beta-release quality, meaning that they have not undergone full validation and may still contain significant errors. </p>
