Project Overview 

The multi-frequency radiometers field campaigns comprise of two one-day campaigns across an approximately two or three weeks’ timeframe. The overall objective of this campaign is to develop algorithms and techniques to retrieve soil profile using K-, L- and P-band radiometers, and to downscale L- or P-band brightness temperature observations and/or soil moisture products using K-band radiometers. The field campaigns involve collecting airborne radiometer data together with ground observations of soil moisture, vegetation water content, soil surface roughness and ancillary data for a diverse range of conditions.
