Model error covariance matrices for atmospheric profile errors. a Estimation from comparison of clear-sky observations over the ocean to model calculations. b, c, d Estimations from Monte Carlo simulation of estimated errors in atmospheric profiles, for b clear sky, c cloudy sky with CTT of 280–300 K, and d cloudy sky with CTT of 280–300 K. Each panel shows an image of error covariance matrix. The row and columns denote ten MODIS bands
