"Intercomparison of active microwave derived surface status and MODIS land surface temperature at high latitudes";

Knowledge about the freeze/thaw state of the surface is
of major importance for climate modelling, hydrology and
numerous other applications. In this study, a freeze/thaw
state detection algorithm using the ASCAT scatterometer is
compared to Land Surface Temperature (LST) from MODIS
as well as to a product derived from ENVISAT ASAR data.
Good agreement with the LST product was found over the
study area in Northern Siberia with disagreement below 22%
for all 8-day periods of 2007. SAR derived surface status can,
if sufficient sampling is available, provide similar results as
with ASCAT but even with higher spatial detail.
