    Last update: 20 June 2018

    GOME Level 2 products were generated by DLR on behalf of the European Space Agency, and are the end result of the Level 1 to 2 reprocessing campaign of GOME Level 1 version 4 data with Level 2 GOME Data Processor (GDP) version 5.0 (HDF-5 format).

    The GOME Level 2 data product comprises the product header, total column densities of ozone and nitrogen dioxide and their associated errors, cloud properties and selected geo-location information, diagnostics from the Level 1 to 2 algorithms and a small amount of statistical information.

    Data Set Specifications
    Spatial coverage: 90 N, 90 S, 180 W, 180 E
    Temporal coverage: 1995-06-28 - 2011-07-02
    Starting from July 2003, products have reduced orbital coverage due to permanent failure of the ERS-2 Low Bit Rate on-board storage capability. Data could not be stored on-board any longer, and only direct transmission to on-ground receiving stations distributed over the globe was possible.
    Current Processor Version: GDP 5.0
    Processing level
    Level 2
