MERIS Level3 Products
2007-01-15


The first set of products are marine products:
  • Chlorophyll Concentration for the open ocean (case I)
    Chlorophyll concentration is a very convenient measure of abundance of phytoplankton biomass, which has an important role in fixing CO2 through photosynthesis.
  • Water leaving radiances at 412, 443, 490, 510 and 560 nm.
  • Aerosol optical thickness at 865 nm and the angstroem coefficient.
    The aerosol retrieval is an important step in the atmopheric correction, but it also gives an indication on the status of the atmosphere (pollution, dust storm...etc).

The second set of products are land products:
  • The aerosol optical thickness at 443 nm and the angstroem coefficient.
    The aerosol properties give information on the air quality and aerosol types over land. It can be used as well to correct the land reflectance from the atmospheric effect.
  • The MERIS Global Vegetation Index (MGVI)
    The MGVI is the Fraction of Absorbed Photosynthetcally Active Radiation (FAPAR) calculated from MERIS data. It is a fundamental parameter for monitoring the state of the vegetation and for the environmental studies. It represents the fraction of the solar energy absorbed by the vegetation which is the key parameter for the photosynthetic process.
The third set of products are atmosphere products:
  • The water vapour over clear sky
    Water vapour is the most effective greenhouse gas in the atmosphere. It influences weather and climate and is responsible for cloud development, precipitation, and modulates the atmospheric radiative energy transfer.
    It effects weather and climate and is responsible for cloud development, precipitation, and modulates the atmospheric radiative energy transfer. Therefore it influences the energy balance of the earth and, in turn, also effects the temperature and circulation of the earth-atmosphere system.
In addition, two other quality products have been processed:
  • The aerosol optical thickness at 550 nm both over land and sea.
  • The repartition of the ABSO_DUST flag
    The ABSO_DUST flag represents the Dust-like absorbing aerosol selected for atmosphere correction.
