MERIS was a push-broom spectrometer launched aboard the European Space Agency's (ESA) ENVISAT-1 spacecraft along with 9 other instruments. MERIS consisted of five cameras aligned side by side to provide a wide field-of-view of the Earth, which it could image in 3-days. The sensor had a swath width of 1150 km and measured the Earth's reflected radiation in 15 spectral bands.
The MERIS sensor is no longer operational. The ENVISAT mission collected data from 2002 until 2012 when communication with the satellite was unexpectedly lost.
MERIS data are provided and multiple processing levels and at 3 resolutions - Low, Reduced, and Full. The MER_FRS_BP product is a full-resolution (260m x 290m) browse product."

|File Naming Convention:
- XXX = the product mode, or contains letters used to differentiate between products created at the same processing level
- Y = the product level code (0, 1=1B, 2, B=browse)
- Z = indicator for product Parent (segment) or Child (extracted).
- p = processing stage flag (N = Near Real Time, V = fully validated, T = test, S = special)
- GGG identifies the center which generated the file
- yyyymmdd is the start day of the acquisition,
- HHMMSS is the start time of the acquisition,
- tttttttt is the duration (in seconds) of the acquisition,
- P identifies the phase of the mission,
- ccc is the number of the cycle in the mission phase,
- OOOOO is the relative orbit number within the cycle,
- aaaaa is the absolute orbit number,
- QQQQ is a numerical wrap-around counter for quick file identification. For a given product type the counter is incremented by 1 for each new product generated by the product originator.
- SS identifies the satellite (E1 = ERS-1, E2 = ERS-2, N1 = ENVISAT-1).
- GGG identifies the center which generated the file:
