ESA CCI SM v2.2, 2014-03-17
---------------------------
- Project internal release
- the temporal coverage is now Nov-1978 to Dec-2014
- improvement in the flagging of the active data where extreme high and low
  values are filtered

ECV SM SM v2.0, 2014-07-10
--------------------------
- release to the general public
- bug fixes
- five ancillary data sets provided in addition to the three data products:
  * Global land mask used in the ECV SM v02.0 products
  * Global porosity map derived by applying soil water characteristic equations of 
    Saxton and Rawls (2006) to texture data of the Harmonized World Soil Database v1
  * Global AMSR-E VUA-NASA Vegetation Optical Depth averaged over the period 2002-2011
  * Global topographic complexity
  * Global Wetland fraction
