NOAA-14 Calibration Data for Operational Use ============================================ NOTE: All file names refer to files in the 'jwocky' anonymous FTP account, in the directory '/pub/sbuv/mcnamara'. PMT Temperature Correction ************************** The correction to the radiometric response for photomultiplier tube (PMT) temperature variations is unchanged. Please see Table 13.2 of the "NOAA-14 A&E Phase Final Report" for the format and coefficients of this algorithm. Non-Linearity Correction ************************* The correction to the instrument response for non-linearity effects is unchanged. Please see Table 13.3 of the "NOAA-14 A&E Phase Final Report" for the format and coefficients of this algorithm.
