Abstract

For the proper radiometric calibration of the CrIS sensor it is imperative to provide high quality characterizations of the ILS and the spatial response of the sensor. The methodology for determining the self-apodized ILS using both a laser and gas cell measurements is discussed with emphasis on the updates to the gas cell methodology. These methods for characterizing the self-apodized ILS have recently been exercised using the CrIS Engineering Development Unit. A description of the test configuration, data collection and data analysis is presented. Finally, the results are presented for the ILS determination are presented.
