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.
