Near-Real-Time NO2 Maps from ERS-2/GOME

This site provides one-day composites of total column nitrogen dioxide from the Global Ozone Monitoring Experiment aboard ESAs ERS-2 in near-real-time. For DLR Level 3 data or image access browse our archive (HDF, GIF, TIFF, Postscript).

Due to the failure of the tape recorder of ERS-2 on June 22, 2003 the data coverage of GOME had been limited to the ESA Ground station network in the northern hemisphere (Latest news on ERS-2 can be found here).

On behalf of ESA, the DLR Antarctic Receiving Station at the O'Higgins base was acquiring additional GOME instrument data from the ERS-2 satellite from October 11 to December 3, 2003. This valuable data allowed near-real time monitoring of the ozone hole over the South Pole using ERS-2 to resume. The O'Higgins receiving station is operated by the German Remote Sensing Data Center (DFD) of DLR.

Thanks to the cooperation between ESA and DLR and with the support of KONGSBERG SPACETEC in Norway, the DLR Antarctic Receiving Station was online from October 11 to December 3, 2003 and was archiving the GOME data collected within its communication cone. This was the first time that near-real-time data are being sent from O'Higgins to DLR in Oberpfaffenhofen, Germany.

The near-real-time products from the Global Ozone Monitoring Experiment aboard ESAs ERS-2 are computed operationally at DLR within the N-GONG project (Near-real-time Global Ozone Network from GOME).

The European Space Agency (ESA) is acknowledged for the GOME Level 2 data. Special thanks to the ERS-2 receiving stations Kiruna (operated by SSC), Gatineau (operated by NRCan) and Maspalomas (operated by INTA)
