Data Download (ESA CCI SM v03.2)

This global ECV soil moisture data set has been generated using active and passive microwave spaceborne instruments and covers the 37 year period from 1978 to 2015. The data set consists of three products: an active data set, a passive data set and a combined data set. It provides daily surface soil moisture with a spatial resolution of 0.25 degree.

Besides the extended temporal coverage it now also includes the new sensors SMOS and MetOp-B ASCAT.

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 and MetOp-B.

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, GCOM-W1 AMSR2, and SMOS.

Further characteristics are improved weighted merging based on signal-to-noise-ratio estimates and improved temporal sampling for most periods. The new release also provides improved estimates of random errors and enhanced metadata descriptions. Random errors are better described as well as metadata.
