•Model predictions
– Moisture content
at the surface layer (2cm), root zone layer (1m) and the whole soil profile
–Period : 1987-1988
•SMMR
–at the very thin top surface (1cm), period: 1979-87
•In-situ measurements
–Plant-available SM: originally recorded as percent
wetness by mass of dry soil->volumetric SM
–> subtract volumetric SM at wilting level -> Plant-available SM
–Different datasets
(Russia (130 stations, 1978-85, Mongolia
(42 stations, 1964-93), China (43 stations, 1981-91)
cover different years
•Three datasets with different soil moisture definitions,
how will we compare them?
