Version and history



Processing version


MERIS Level 1B, Level 2, auxiliary and intermediate products stored in the database have been processed by MEGS, the MERIS prototype ground segment. Some in-situ water-leaving reflectances are also normalised with MERIS bidirectionality look-up tables.

MERMAID users are thus strongly encouraged to pay attention to the processing version.

Current available versions:

  • MEGS 7.5.1 in Reduced Resolution (identical to MERIS 2nd reprocessing but with updated geolocation)
  • MEGS 8.0 in Reduced Resolution (MERIS 3rd reprocessing)

History
