A New Approach for Albedo Calibrationi on OMPS

Ball Aerospace and Technologies Corp. is building the third build of the Ozone Mapping and Profiler Suite, which measures daily ozone using three spectrometers that cover a wavelength range from 250 nm to 1000 nm. The radiometric calibration of the sensors is albedo-based, and a new method is being used for the JPSS-2 delivery. The new method is a direct, accurate, and more robust measurement of albedo where a single source is used to measure both radiance and irradiance responses with only a short amount of time between the measurements. This independent measurement of albedo will have improved wavelength-dependent uncertainties because the small temporal separation in the measurements minimizes changes in both sensor and source. This presentation details the motivation, setup, and initial results of the independent albedo measurement
