SMAP Enhanced L3 Radiometer Northern Hemisphere Daily 9 km EASE-Grid Freeze/Thaw State V001

Version 001 eng
  • Abstract
    Daily global composite of up-to 30 half-orbit L1C_TB files and estimated binary freeze/thaw state based on passive normalized polarization ratio measurements by the SMAP radiometer during descending and ascending half-orbits at approximately 6 AM or 6 PM local solar time, respectively.
  • Purpose
    The SMAP L3_FT_P_E algorithm provides daily global composite of freeze/thaw state based on radiometer brightness temperature data on a 9 km grid.
