  3. NOAA Support to GDWGActivities • NOAA GDWG focusedon • Building the GSICS Action Tracker on the Google Cloud. • Now supports extraction of EP Actions • Maintaining the GSICS Wiki on the AOSC Webserver ( • Develop script that download GSICS Products from THREDDS Server ( provided to EUMETSAT for review) • Developed Product Catalog with Quicklook for GSICS product • Support reviewprocess • Futurework • Migrating wiki • Developing ActionTracker • Frascati, Italy GRWG/GDWG meetingpresentations A 3

  4. Support to GDWG Activities • Mirroring GSICS Product: All GSICS products currently copied on NOAA servers routinely. Work underway to put it online via ftp (discussion in 9d) • New Action Tracker-> Action Tracking on Cloud (discussion in 9k) • Updates on Action Tracker (Parser for EP Meetings, Activate Link option added, Column Width adjusted to browser) • New GSICS Product Catalog Prototype developed that has capability of Product Monitoring and product Visualization. Click here (discussion in 9i) • Developed Fortran interface for IASI-EPS reader, provided it to GRUAN community. • GOES-13/15 [01/18/2010- 17/12/2017] NOAA now accessible via GSICS Products Catalog (Process underway to make other NOAA products online )

  5. Support to GRWG Activities - MW ATMS biases compared to GRAS RO Courtesy X. Zou, Univ. of Maryland • NOAA co-chairs the MW subgroup (R. Ferraro) and has several key members in the group: • M. Bali, C-Z. Zou, T. Reale, M. Liu, H. Meng, B. Ho • Several other affiliates involved • Major activities include: • Extending membership to the group from the international community • MW related articles in the quarterly newsletter • Interacting with other calibration communities: CEOS, GPM, etc. • ATMS calibration • Major achievements in the past year: • Convened four meetings of the MW subgroup • Closing the loop on SNO best practices and MWI LUT’s • NOAA actions include: • RTM intercomparison leveraging GRUAN colocations • Best practices • MW calibration references – GPSRO, AMSU CDR’s N20 ATMS SDR Biases Courtesy H. Yang, Univ. of Maryland

  6. NOAA GPRC – quantifying differences between ATMS and AMSUs Example of SNPP-NOAA-20 ATMS CH11 difference TDR Double difference NPP – NOAA-20 ~ 0.20 K USING ECMWF AS A REFERENCE FOR DOUBLE DIFFERENCE

  7. Difference between ECWMF and GPSRO in Double Difference Calculation is ~ 0.05 Using GPSRO - Double difference ~ 0.25 TDRs ~-0.5 ~-0.25 USING GPSRO AS A REFERENCE FOR DOUBLE DIFFERENCE

  8. Double difference: [RT – NPP] – [RT –N20] (RT=0) Is there an advantage of two satellites in the same exact orbit for intersatellite calibration? From Isaac Moradi April 7,2019

  9. During the Provisional Review Time, we observed the orbit-shape difference between SNPP LST and N20 LST . Mitch suggested that such difference may be significantly reduced in the mean LST difference of certain time period at least cover one orbit-repeat period. The LST team made up the mean differences images and plots then, illustrated in the next few slides.

  13. LEO-LEO Inter-Calibration Dave Tobin

  14. GEO-LEO: Double Difference Using G16 ABI as the Transfer • N20/CrIS, NPP/CrIS, Metop-A/IASI and Metop-B/IASI are all stable within the study period. • The calibration difference is less than 0.1K among the four reference instruments • N20/CrIS is slightly warmer than NPP/CrIS. N20/CrIS is slightly warmer than NPP/CrIS Double Difference between N20 and NPP CrIS Double Difference between IASIA and IASIB Double Difference between NPP/CrIS and IASI-B Metop-A/IASI and Metop-B/IASI is in general well with ~±0.1K Metop-B/IASI and SNPP/CrIS is in general within ~±0.1K

  15. Support to GRWG Activities UV Subgroup • NOAA is participating in all four UV Subgroup projects • Leading the Ozone Profile Measurement residual comparison study – currently working with NOAA SBUV/2 and OMPS NP instruments. We are creating time series to track the V8Pro initial residuals for the nine profile channels from 253 nm to 313 nm for operational and reprocessed data sets. • Participating in the UV reflectivity channel comparison study – currently working with NOAA OMPS NM and EUMETSAT GOME-2. We are tracking statistics on reflectivity and UV absorbing aerosol index values over the Equatorial Pacific. We are looking forward to working with the Vis Subgroup and their Rayleigh calibration project. • Participating in the solar reference and comparison study. We are modelling OMPS solar measurements with comparison to proxies from multiple sources. We are creating Mg II Index time series from OMPS NP and GOME-2 products. • Participating in the Best Practices for Calibration project. L. Flynn is working on a NESDIS Technical Report to capture the experiences and lessons learned from trending and error analysis of hyperspectral UV instrument measurements. • NOAA is providing monitoring of our Level 2 and Level 1 products at
