Abstract
This presentation is a follow-on to the Radiation Budget Instrument (RBI) spectral calibration plan presented last year [1]. During the past year SDL has refined the RBI spectral calibration plan and replaced modeled and estimated spectral calibration performance values with chamber-validation-test values collected using the Absolute Cavity Radiometer (ACR) and the spectral reference detector (SRD) [2]. This presentation focuses on the progress, uncertainty estimate updates, and confidence gained over the past year that we will meet the RBI spectral calibration requirements, which are both challenging and critical to overall mission success.
1) Background information on RBI program, instrument, and spectral calibration requirements can be found in last year’s presentation, “200 nm to 100 µm, with Extremely Low Uncertainty Requirements: Meeting the Challenges of the RBI Spectral Calibration”, Proceedings of the 2016 Conference on Characterization and Radiometric Calibration for Remote Sensing, Logan, UT, Aug. 2016.
2) The SRD was built by Harris and delivered to SDL. It is similar to the RBI flight detector total band in spectral responsivity and performance.
