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.
The instrument scans the Earth's surface
by the so called "push-broom" method. Linear CCD arrays
provide spatial sampling in the across-track direction,
while the satellite's motion provides scanning in the
along-track direction.
MERIS is designed so that
it can acquire data over the Earth whenever illumination
conditions are suitable. The instrument's 68.5° field of
view around nadir covers a swath width of 1150 km. This
wide field of view is shared between five identical
optical modules arranged in a fan shape configuration.
