operational code updates and test data
Operational Code Updates and Test Data
  • All operational code updates to MX 7.1 based on Mike Wilson’s note “MX7_by_upgrade.docx”
  • Test data sets include
        • CrIS SDRs: 2692 granules
        • ATMS-REMAP-SDRs: 2692 granules
        • Surface Pressure/Land Fraction data: 2692 files
        • ECMWF match-up validation data: 2656 files
        • 2656 granules are used for performance evaluation
offline science code updates and test data
Offline Science Code Updates and Test Data
  • Offline science code updates to MX 7.1 based on Mike Wilson’s note “MX7_by_upgrade.docx”
  • Test data sets provided by STAR/NOAA
        • CrIS SDRs: 2673 granules
        • ATMS-REMAP-SDRs: 2698 granules
        • Surface Pressure/Land Fraction data: 2698 files
        • ECMWF match-up validation data: 2698 files
        • 3 CrIS SDR granules with read errors, so only 2670 granules are used for performance evaluation
focus day data sets on the g ada vs star noaa
Focus Day Data Sets on the G-ADA vs. STAR/NOAA
  • Focus Day data sets are not exactly matched on the G-ADA vs STAR/NOAA
    • Latitude/Longitude, CrIS SDRs and ATMS-REMAP-SDRs are not exactly matched

summary evaluation of crimss focus days on g ada mx7 1
Summary: Evaluation of CrIMSS Focus Days on G-ADA Mx7.1
  • Comparisons of profile statistics between NG offline ‘Mx7.1’ science code retrievals and Mx7.1 G-ADA retrievals show close agreement for Sept 20, 2012 focus day
  • Comparisons of percentage yields between NG offline ‘Mx7.1’ science code and STAR offline ‘Mx7.1’ science code similar for final MW+IR convergence that meet chi-square criteria
  • Comparisons of mapped ECMWF fields with offline ‘Mx7.1’ science code and Mx7.1 G-ADA show close agreement, although Mx7.1 typically warmer and dryer in some regions
  • Next Step: Processing Feb 3, 2013 focus day on G-ADA with all Mx7.1 code updates; G-ADA processing of CrIS and ATMS remapped SDRs complete
