This analysis investigates in-flight spectral transmission variations in the MicroCarb instrument caused by ice deposition on detectors and band-pass filters. By reviewing the optical architecture of the SWIR spectrometer, the study correlates transmission fluctuations and stray light behavior with environmental operational temperatures. These findings inform calibration strategies to maintain precise carbon dioxide monitoring throughout the mission lifecycle.
