Paper Abstract

The present GOES imager exhibits East-West stripes in IR images due to low frequency errors in the calibration of the adjacent North-South detectors. Striping makes delineating boundaries of structures in images difficult, especially in the case of cold scenes. A computer program has been developed that generates simulated IR images using detector noise parameters as inputs. The simulation includes errors due to background drift between space clamps, drift during a space clamp, and errors determining the first order gain during the internal blackbody calibration. The results of the simulation agree well with on orbit measurements of GOES 8 and 9 striping in channels 4 and 5. These simulations can also predict striping performance of future GOES imagers from detector noise parameters allowing for improved detector selection constraints.
