Abstract :
Triple collocation error estimation is a powerful tool to simultaneously estimate the error structure and calibrate a set of independent observations. In this study, we use this technique to estimate the errors of a passive microwave (TRMM-TMI) derived, an active microwave (ERS-2 scatterometer) derived and a modelled (ERA-Interim reanalysis) soil moisture data sets.
