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
