Paper Abstract

The objective of the current research is to minimize the theoretical uncertainty of the CERES ERBE-like level 1 instantaneous filtered and unfiltered radiance data products. The instrument's measured digital counts are converted to a filtered radiance by means of instrument calibration coefficients. The filtered radiance is then converted to an unfiltered radiance with an algorithm that utilizes the instrument's spectral response function. Uncertainties in the calibration sources and the spectral response function of the instrument can negatively affect the quality of the final data products. To reduce this effect, we are seeking to increase our understanding of the relative impact that various instrument and calibration parameters have on the level-1 filtered and unfiltered data products. Results of a statistical study of data products sensitivity to various instrument and calibration parameters are presented. The sensitivity of the level-1 data products to the spectral response of the instrument when viewing non- Planck Earth scenes is also discussed.
