Tropospheric NO₂ from GOME for MINOS

Introduction:

• Transport of pollution from Europe and from remote sources
• Chemical mechanisms that contribute to the build-up of oxidants and aerosols
• Export of pollutants to the global environment, e.g. towards SE Asia
  

In support of MINOS, tropospheric excess columns of NO2 as derived from measurements of the Global Ozone Monitoring Experiment (GOME) are made available on this site. The tropospheric excess column is defined as  the integrated tropospheric NO2 amount that is in excess of that measured above a clean air reference sector, usually the Pacific. As plots shown on this page are derived from GOME Near Real Time measurements (courtesy of ESA/ESRIN/DLR), no data from the Pacific sector are available. We therefore use the Atlantic as a clean air reference, which might lead to underestimation of the real tropospheric columns. Please note, that no cloud clearance has been applied to the data. Therefore, regions covered with clouds can be misinterpreted as regions with low tropospheric NO2 abundances! 
More details on the analysis procedures can be found in the references given below.

Data:

The plots below are produced automatically and are based on the GOME Near Real Time data. Usually, plots should be available with a delay of one day, but as there is no extra funding for this web page, maintenance does not have a high priority. If you experience any problems, please contact Andreas Richter.

We will try to add some more GOME NRT data products here soon. If you have any requests, please contact Andreas Richter.
