Data Download (CCI SM v02.2)

This global ECV soil moisture data set has been generated using active and passive microwave spaceborne instruments and covers the 36 year period from 1978 to 2014. The data set consists of three products: an active data set, a passive data set and a merged data set.

The active data set was generated by the Vienna University of Vienna (TU Wien) based on observations from the C-band scatterometers on board of ERS-1, ERS-2 and METOP-A.

The passive data set was generated by the VU University Amsterdam in collaboration with NASA based on passive microwave observations from Nimbus 7 SMMR, DMSP SSM/I, TRMM TMI, Aqua AMSR-E, Coriolis WindSat, and GCOM-W1 AMSR2.

The active, passive and merged products are freely available after completion of a simple registration. User Registration can be found here.
