  3. Example using AIRS sample fromDec 2011

  4. Mean SD RMS AIRS QC Pass RMS Bias SD

  5. Mean SD RMS AIRS QC P + F

  6. Max / Min Differences AIRS QC P + F

  7. Max / Min Differences AIRS QC Pass

  8. NWP baseline AIRS QC Pass

  9. Profile Mean baseline AIRS QC Pass

  10. Profile Mean baseline No AIRS QC

  11. Negative SD seems isolated to cases where mean is one-sided, positive large ..

  12. CrIMSS Validation ExampleOct 14-18

  13. CrIMSS QC definitions:High (IR + MW) … 15%Low (IR only) … zeroLow (MW only) … 65%Poor (non-converge) … 20%NUCAPS QC definitions: Pass … 20%Fail … 80%(… only fgess available)

  14. CrIMSS 42 levels CrIMSS QC (remove Poor) … Baseline

  15. Base + NUCAPS QC (pass)

  16. Base + IASI QC (pass)

  17. Base + AIRS QC (pass)

  18. Base + CrIMSS QC (high (IR + MW))

  19. Base + NUCAPS QC (pass) + CrIMSS QC (high (IR + MW))

  20. CrIMSS Validation ExampleOct 30th NUCAPS … retrieval only (untuned)

  21. CrIMSS QC (remove Poor) … Baseline Base + NUCAPS QC (pass) + CrIMSS QC (high (IR + MW))

  22. … NUCAPS now indicated as “Retrieval” NUCAPS CrIMSS QC (remove Poor) … Baseline

  23. CrIMSS QC (remove Poor) … Baseline

  24. Base + NUCAPS QC (pass) + CrIMSS QC (high (IR + MW))

  25. Base + NUCAPS QC (pass) + CrIMSS QC (high (IR + MW))

  26. CrIMSS IDPS 42 levels ? averaged over 1km T and 2km H20 Lower levels 100m apart profiles begin 500m (T) and 1km (H20) above srfc gap from 30 to 10 hPa

  27. Summary • Slow progress toward full access of CrIMSS, NCAPS and MiRS operational data streams • Inconsistency with weighted mean Moisture fraction calculation appears sample characteristic related • Not getting full compliment of NUCAPS products • QC definition ambiguities • CrIMSS 42 levels ?? • Preparing to access Special ARM datasets (and Beltsville)
