Abstract

The Clouds and Earth's Radiation Energy System Project is flying two instruments on both the Terra and Aqua spacecraft. In order to produce highly accurate measurements of the Earth's radiation budget, several calibration and validation techniques are employed on the ground and in orbit. Three editions of data products are generated, with modifications made in successive editions to reduce or eliminate errors. Edition 3 incorporates changes based on these tests, which include comparisons of the various channels on both spacecraft. Use of measurements comparing the different channels of the various instruments causes any remaining errors in the instrument data products to be related among the channels. An error analysis is presented which uses information theory to account for the many tests and checks to give the errors of the instrument data products and the correlations among them in the Edition 3 instrument data products.
