Global Ozone Monitoring Experiment (GOME) Data Products from the Institute of Environmental Physics and Remote Sensing (IUP/ife), Germany

Since the support of NRT GOME Level-2 data (total ozone) has been continued, total ozone maps from the same day are still provided on this web site. The 1-day total ozone images are updated every six hours. The ozone maps are produced at ife/iup using the Level-2 data (total columns of ozone) provided from the new Kiruna-based GDP (GOME Data Processor) of the DLR/DFD.

The ESA station in Kiruna is one of five ground stations receiving the global ERS-2 transmission. Ten out of the daily fourteen GOME orbits are transmitted to Kiruna. In the near future three additional orbits from the Mapolamos and Gatineau stations will be also available.

The ozone vertical profiles are generated at the University of Bremen using the GDP Level-1 data (radiometrically calibrated sun and earthshine spectra). GOME Global Ozone Distributions ------------------------------- With the current scan strategy (960-km swath) it takes GOME three days to achieve global coverage (for details see the GOME instrument description). For each month (beginning with July 1996) the plots on this page show four three-day periods of GOME measured total ozone values as indicated in the plot titles.

This gives an impression of the evolution of the global ozone distribution during one month. Vertical column amounts of ozone are operationally derived from the GOME spectra at DLR-DFD using the DOAS method. At ife/iup the irregularly spaced measurement points are gridded to a regular lat-long grid before being mapped.

White space on the maps is due to data gaps. [
