Improvements to Ozone Mapping Profiler Suite Sensor Data Records

The Ozone Mapping Profiler Suite (OMPS) Sensor Data Records (SDRs) provides critical inputs to the Environment Data Records (EDRs) to continue US mission of global ozone monitoring. The SDRs algorithm and algorithm Look Up Tables perform the necessary processing steps to remove and correct sensor effects that are inherent to the sensor hardware. Recent improvements have been made in radiometric and spectrometric calibration that significantly improved albedo calibration accuracy, such as wavelength, radiance/irradiance coefficient and stray light. These improvements have elevated OMPS SDR at the sensor attainable level that meets the SNPP users’ requirement. The sensor calibration and its associated SDR algorithms have been further evaluated and modified so that we can now present the results of continued monitoring of the SDR performance. We focus particularly on the calibration methodology and algorithm while we offer lessons learned during the four plus years of operation of OMPS.
