Applications of GOES-16 ABI Lunar North-South Scan (NSS): Detector Out-of-Field, Blooming and Uniformity Responses

During the GOES-16 Advanced Baseline Imager (ABI) Post-launch product testing (PLPT) period, a series of the special scans of North-South Scans (NSS) were conducted across the Moon when it transited across the space within the ABI field of regard (FOR). These lunar NSS collections ensured that all the detectors of each ABI channel scanned across the illuminated lunar surface. As there is no atmosphere over the lunar surface, the lunar NSS data provide an unique opportunity to characterize the out-of-field (OOF) response and blooming effects for each detector. Preliminary results show no strong OOF and blooming effects for each detector at the VNIR bands. The detector response uniformity, especially for the detectors from the same column at the focal plane modules, are also characterized using the NSS data with very small uncertainty. The same technique and method will be applied to the future GOES-R series ABI during their PLPT periods. More details and updates, if any, will be presented in the coming meeting.
