Description
Summary:Two overlapping efforts help to characterize the Geostationary Lightning Mapper (GLM) performance. The Post Launch Test (PLT) phase validates the predicted pre-launch instrument performance and the Post Launch Product Test (PLPT) phase validates the lightning detection product used in forecast and warning decision-making. This presentation documents the calibration and validation activities for the first 6 months of GLM on-orbit testing and validation commencing with first light on 4 January 2017. The PLT phase addresses image quality, on-orbit calibration, RTEP threshold tuning, image navigation, noise filtering, and solar intrusion assessment, resulting in a GLM calibration parameter file. The PLPT includes four main activities, the Reference Data Comparisons (RDC), Algorithm Testing (AT), Instrument Navigation and Registration Testing (INRT), and Long Term Baseline Testing (LTBT). A field campaign also provided valuable insights into the GLM performance capabilities. The PLPT tests each contribute to the beta, provisional, and fully validated GLM data.
