Envisat :EnviSat is an Earth observation mission of ESA (European Space Agency). The overall objectives are: studying and monitoring the Earth's environment on various scales, from local through regional to global.
Envisat/MERIS :MERIS is a passive optical pushbroom wide-field instrument (CCD technology) intended to measure reflected radiation the Earth's surface, the ocean, and from clouds with high spectral resolution

Filter Description

Filter ID (?) :Envisat/MERIS.band12
Description (?) :MERIS band 12 nominal spectral response
Phot.System (?) :MERIS
Detector Type (?) :Energy counter
Band Name (?) :------
Obs. Facility (?) :Envisat
Instrument (?) :MERIS
Comments (?) :Nominal Spectral Response Function computed from MERIS Spectral Model 2004 - the official one for 2nd and 3rd reprocessings - but forcing central wavelengths to their theoretical values , hence compatible with the Level 2 processing algorithms and look-up-tables. Spectral characteristics used to compute the SRFs other than response centering, namely those defining the SRF of individual CCD cells, have been obtained by averaging over cameras.
