Background Radiation Measured by the ALADIN Instrument

Kurzfassung

According to the DISC project management plan [1] the radiometric performance of the ALADIN instrument is permanently monitored and investigated. This task is part of the work packages WP 300 (Assessment of Instrument Performance and Data Product Quality), WP 4100 (Data Quality and Monitoring for L1B and Calibrations), and WP 4150 (Algorithm Consolidation Studies for L1B and Calibrations). It is assigned to the following two task ID’s at [2], providing a task overview for EDAFECS. - Task ID 10003 : SBG signal analysis (within the topic Analyzing Aeolus Dark Measurements) - Task ID 50002 : radiometric check (within the topic Sense the HLOS wind) In the present technical note (TN), the first item is dealt with. Results of the monitoring and special investigations of in orbit L1B Rayleigh and Mie solar background (SBG) signals and their ratios of the whole mission lifetime are presented and discussed.
