High Mountain Asia ASCAT Freeze/Thaw/Melt Status V001
-
Abstract
This data set contains bulk landscape frozen or thawed status over seasonally frozen land as well as snowmelt status over glacierized areas for the High Mountain Asia region. Daily Freeze/Thaw/Melt (F/T/M) status is derived from vertically polarized (V-pol) C-band (5.255 GHz) backscatter measurements acquired by the Advanced Scatterometer (ASCAT) on EUMETSAT Metop-A and Metop-B satellites. Swath-ordered observations are spatially enhanced using the Scatterometer Image Reconstruction (SIR) algorithm (Early and Long, 2001), are posted on Earth-fixed 4.45 km grids, and are interpolated to a daily product from the original 3-day, a.m. overpasses. -
