Mar 13, 2021 · In this study, the lifetime LGS gains are validated by the lunar calibration coefficients (defined as F-factors) using a lunar irradiance model.
When records have sharp change or drifts that means new events might have occurred over the sensor operation period, and calibration might need to be updated.
