Welcome to the ESA DUE GlobVapour Project

The GlobVapour project is funded by the European Space Agency (ESA) Data User Element (DUE) programme.

The DUE mission is to encourage the establishment of a long-term relationship between User Communities and Earth Observation.

The DUE GlobVapour project aims at generating validated multi-annual global water vapour datasets with error estimates.


April 2012

ESA DUE GlobVapour project has been finalised in March 2012
Final Products are available online

by Dr. Marc Schröder (ESA DUE GlobVapour Project Manager)


We are proud to announce, that the final GlobVapour data are now available on this web page. Please sign in for data access via ftp.


Among other achievements, two long-term satellite-retrieved global total column water vapour (TCWV) data sets are the result of two years of work within the ESA DUE GlobVapour project. First, a combined data product from the sensors SSM/I (0.5° over ocean) and MERIS (0.05° over land) was derived for the time period 2003 - 2008. Second, data of the sensors GOME, SCIAMACHY and GOME-2 have been homogenised for the time period 1996 – 2008. TCWV is given in units of kg/m2 and stored in NetCDF files, that are fully compliant with the NetCDF Climate Forecast convention. Both products are daylight data with a spatial resolution of (0.5°)2 and include the standard deviation, number of observations and retrieval error (only SSM/I+MERIS).


The GlobVapour final products are fully documented: Algorithm Theoretical Baseline Documents (ATBD), Product Validation Reports (PVR) and the Product User Guide (PUG) are available on this web page.


The GlobVapour is highly interested in continued or new cooperation on data studies and applications. Your feedback on GlobVapour products is very welcome and might impact future directions of future project achievements.


Technical features of SSM/I+MERIS products:

  • daily composites and monthly means
  • spatial resolution of 0.5° is available on ftp server
  • a version in high resolution (0.05°)² is available on request
  • SSM/I clear-sky data are available on request

Technical features of GOME/SCIAMACHY/GOME-2 product:

  • weekly and monthly means
  • homogenised data set: the sensor GOME covers 1996-2002, SCIAMACHY 2003-2006 and GOME-2 2007 and 2008
  • global data set (over land and ocean)
