High Mountain Asia ASCAT Freeze/Thaw/Melt Status V001

Version 1 eng; usa
  • Abstract
    This Level-3 (L3) product provides freeze/thaw/melt (F/T/M) status over seasonally frozen land and snowmelt status over glaciated areas for high mountain Asia glacier and snow regions. Daily F/T/M status is derived from vertically polarized (V-pol), C-band (5.255 GHz) Advanced Scatterometer (ASCAT Metop-A and Metop-B) backscatter measurements. Swath-ordered observations are spatially enhanced using the SIR algorithm (Early and Long, 2001), are posted to an Earth-fixed, Northern Hemisphere azimuthal 4.45 km grid, and are interpolated to a daily product from the original 3-day, a.m. overpasses.
