Paper Abstract

The calibration requirements for an earth observing imaging spectrometer system can be derived for specific applications. For the case of the detection of ocean chlorophyll a method of defining the minimum calibration requirements in relation to the required measurement accuracy is described. An end-to-end simulation including the effect of chlorophyll on ocean reflectance, the effect of the atmosphere, satellite system detection efficiency, noise and calibration uncertainty and of the inversion process is described. It is shown that for the proposed ESA NERIS instrument an inversion process based on the use of singular value decomposition methods places reduced constraints on the requirement for absolute accuracy and leads to similar requirements for relative calibration as the more conventional band ratio methods.
