1. Find Collocations

A set of observations from a pair of instruments within a common period (e.g. 1 day) is required as input to the algorithm. The first step is to obtain these data from both instruments, select the relevant comparable portions and identify the pixels that are spatially collocated, temporally concurrent, geometrically aligned and spectrally compatible and calculate the mean and variance of these radiances.
