10. Apr. 24, 2009STAR Cal/Val Team Meeting Page 10 Future Work NOAA-19 SBUV2 is in normal operational mode. Its calibration procedure needs improvements. The online SBUV2 Cal/Val software for operational data is ready to include NOAA-19 (when its calibration is finalized) --- weekly process). Develop a software for the internal SBUV2 data --- (monthly process). Expend capabilities of the online CalVal software by including more diagnostic variables related to SBUV2. Comparison with OMI/GOME2 measurements.
