Error characterisation of global active and passive microwave soil moisture datasets [PDF]
Hydrology and Earth System Sciences, 2010 Understanding the error structures of remotely sensed soil moisture observations is essential for correctly interpreting observed variations and trends in the data or assimilating them in hydrological or numerical weather prediction models. Nevertheless,

HOAPS precipitation validation with ship-borne rain gauge measurements over the Baltic Sea [PDF]
Tellus: Series A, Dynamic Meteorology and Oceanography, 2012 Global ocean precipitation is an important part of the water cycle in the climate system. A number of efforts have been undertaken to acquire reliable estimates of precipitation over the oceans based on remote sensing and reanalysis modelling.
