SMAP L3 Radar Northern Hemisphere Daily 3 km EASE-Grid Freeze/Thaw State V003

Version 003 eng
  • Abstract
    Daily global composite of up-to 30 half-orbit L2_FT_A binary freeze/thaw state based on radar backscatter measurements by the SMAP radar during descending and ascending half-orbits at approximately 6 AM or 6 PM local solar time, respectively.
  • Purpose
    The SMAP L3_FT_A algorithm provides daily global composite of freeze/thaw state based on synthetic-aperture radar data on a 3 km grid.
