  1. OMPS SDR Data Quality via the Satellite Integrated Calibration/ Validation System (ICVS) M. Grotenhuis and X. Wu

  2. OMPS ICVS Overview • STAR Integrated Calibration / Validation System (ICVS) OMPS web site: http://www.star.nesdis.noaa.gov/smcd/spb/icvs/instrument_npp_omps.php • Purpose • Monitor the status of OMPS and its operation • Assist the evaluation of performance of OMPS and its SDR • Assist anomaly investigation and resolution • ICVS Team • Collaboration with ICVS leads for other instruments yields “best practices” for methods of performance evaluation and instrument status/performance visualization

  3. OMPS ICVS Components • Components • High-level Instrument Status • Instrument Status • Operation Status • Instrument Performance • SDR Performance • Trending • Comparison with other instruments

  4. High-Level Instrument Status Total Column Radiance Maps at 331 nm

  5. Instrument Status • Instrument component temperatures/currents/voltages • Motor Currents • Calibrator voltage/current 24 hours 10 days Entire dataset

  6. Operation Status • Correction Table IDs • Table Versions • Correction Flags • Flight Software Information 24 hours 10 days Entire dataset

  7. Instrument Performance • Lamp Image Noise • Shot Noise • Nonlinear Sensitivity • Electronic Bias Other examples shown by C. Pan C. Pan

  8. SDR Performance Trending L. Flynn and Wei Yu

  9. Radiance/Reflectivity Product Comparisons with Other Instruments • Sampling in the target area for OMPS (left)and GOME2(right) • Pixels mapping (zoom) for GOME2 (40km x 80km) and OMPS(50km x 50km) H. Qian & X. Wu

  10. H. Qian & X. Wu

  11. EDR Performance OMPS on Oct. 16 From EDR team GOME-2 on Oct. 16 OOTCO upgrade from MX6.2 to MX6.3 on Oct. 15

  12. From EDR team NCWCP

  13. Plan • Continue monitoring of OMPS status and operation • Automate monitoring of OMPS performance • Begin CAL SDR monitoring • Obtain CAL SDR and monitoring tools from PEATE • Improve EV SDR monitoring • Collaborate with PEATE and EDR Teams and ICVS of other instruments
