    This water leaving radiance (reflectance) and geophysical product is generated systematically from MERIS L1B. It has a coverage of 1150 km x 17500 km and a radiometric resolution of 1.42 X 10-4 at sea level at 442.5nm. The accuracy is as follows:

    • Surface reflectance (ocean) <2 x 10 -4
    • Surface reflectance (Land) < 5%
    • Chlorophyll retrieval < 15 %
    • Yellow substance < 30 %
    • Suspended matter < 15 %
    • Water vapour < 20%
    • Cloud albedo < 2 %
    • Cloud optical thickness ~ 10%
    • Cloud top pressure ~ 40 hPa
    • MERIS Vegetation Index:-N/A

    The file size is 621 Mbytes per orbit and 47 Mbytes per scene.

    Auxiliary data include: Surface identification flags included in the level 1b product Orbit state vector, Time correlation parameters, Latitude, Longitude, altitude and topographic corrections Sun azimuth, Sun elevation, view azimuth, view elevation, Mean Sea Level pressure, Total column ozone, Total column water vapour, Wind speed
