Envisat has on-board the MERIS camera. MERIS is a programmable, medium-spectral resolution, imaging spectrometer operating in the solar reflective spectral range. Fifteen spectral bands can be selected by ground command, each of which has a programmable width and a programmable location in the 390 nm to 1040 nm spectral range. Meris specifications can be found here.
Accuracy: Ocean colour bands typical S:N = 1700
Spatial Resolution: Land & coast: 260m x 300m
Swath Width: 1150km,
Waveband: VIS-NIR: 15 bands selectable across range: 0.4-1.05 micrometers (bandwidth programmable between 0.0025 and 0.03 micrometers)
When doing the search through the GUI called MIRAVI (it seems to only work with Internet Explorer), I found seven entries. A lot of them are very cloudy.
