GOME tropospheric NO2 data
For the European project POET, a complete time series of GOME tropospheric NO2 columns has been created which can be downloaded as gridded monthly averages.
These files are encrypted, for the password please contact Andreas Richter.
GOME tropospheric excess NO2 columns Version 1 (outdated, please use V2 data!).
For a description of the method used to derive the NO2 columns, please see:
Richter, A. and J.P. Burrows, Retrieval of Tropospheric NO2 from GOME
Space Res., 29(11)
GOME tropospheric excess NO2 columns Version 1b (outdated, please use V2 data!).
This data set differs from Version 1 in two points:
This data version is considered to be temporary only but is much more consistent than Version 1 data.
Daily maps of V1b for +/- 60° latitude are also available:
Daily maps of V1b for +/- 60° latitude based on TOMCAT profiles are also available:
This data set differs from Version 1 in several points:
A more detailed description of the algorithm is given in the POET report, inJ. H. Nüß: An improved tropospheric NO2 retrieval for GOME and SCIAMACHY, PhD Thesis, University of Bremen, 2005 (in German)
