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

This site provides one-day composites of total column ozone 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. This was the first time that near-real-time data are being sent from O'Higgins to DLR in Oberpfaffenhofen, Germany. Further data was acquired at O'Higgins from January to March 2004..

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)
