Abstract

The BELHARMONY project responds to the need of the Belgian and international EO community to have improved consistency in time series generated on the basis of a constellation of medium to high resolution satellite sensors.
The harmonisation the multi-sensor time series within BELHARMONY consists of 1) the assessment and correction of radiometric biases at the TOA (Top-of-Atmosphere) level through the application of a set of independent vicarious calibration methods and considering low, medium and high scene brightness values, 2) the derivation of spectral response adjustment factors to compensate for difference in the relative spectral response curves and 3) the use of a common processing chain for the processing of the L1 data up to L2 reflectance and L3 higher level products.
