The post-operational full-mission reprocessing campaign of ERS-2 GOME consolidated data has been completed with an improved instrument processor version (Level-0-to-1 GDP Version 5.1). A new GOME Level 1b dataset has been generated for the 16-year mission period. The new data bring relevant quality improvements for the revised calibration approach, compensating aging and instrument degradation, and provide enhanced accessibility.
