analysis; and (2) superficial soil moisture content data from satellites (e.g., from ASCAT,
AMSR-E and SMOS). The control variables (Nichols 2010 ) of the NILU land DA system
are the following:
•

Surface temperature;

• Mean surface temperature;

• Superficial volumetric water content;

• Mean volumetric water content of the root zone.
