  1. NOAA Efforts and Recommendationson CrIMSS EDR beta/provisional Maturity • Murty Divakarla, C.D. Barnet, • Xiaozhen Xiong, Mike Wilson, Guang Guo, • Antonia Gambacorta, Eric Maddy, Changyi Tan, and Nick Nalli • STAR, NOAA/NESDIS • Xu Liu and Susan Kizer • Langley Research Center • Degui Gu and Xia L Ma • Northrop Grumman Aerospace Systems • Acknowledgements: • Denise Hagan (NGAS), Xingpin Liu, Kevin Garret, SMCD

  2. NOAA-STAR, NASA-LaRC, NGASCoordinated Efforts • STAR/LaRC/NGAS – Source of SDRs/EDRs/Product Evaluations • Provided SDRs and Ancillary Data Needed for • CrIMSS EDR Algorithm Runs at Various Agencies • Provided Matched Data Sets • ECMWF; AVN; AIRS V5.9 Products • Main hub for CrIMSS EDR Product Evaluations • NOAA FTP Site for SDRs and EDRs. • Provide users with help on SDRs and EDR Products • User’s Guide for Focus-Day Data Sets (In Preparation) • Inter-Compare EDR Algorithm Results Generated at STAR, LaRC (CrIMSS Off-line) and NGAS-Science Code/ADA Implementations • Evaluate IDPS EDR Products/DR Verifications • Upgrades/Improvements to CrIMSS EDR Algorithm -> ADL -> IDPS • ftp://ftp2.orbit.nesdis.noaa.gov/smcd/tking/CrIMSS_CALVAL/STAR/Focus_DAYS/FDAY_02242012_V2/ ftp://ftp2.orbit.nesdis.noaa.gov/smcd/tking/CrIMSS_CALVAL/STAR/Focus_DAYS/FDAY_05152012/

  3. CrIMSS EDR EVALUATIONWith ECMWF Analysis Fields and Heritage Algorithm (Aqua-AIRS) Products • EDR Evaluations for Two Focus Days • 02/24/2012; 05/15/2012 • Verification of CrIMSS EDR Quality Flags • Precipitation; Second Stage IR+MW Convergence; First Stage ATMS-only Retrievals • Verification of Global Temperature and Water Vapor Fields with ECMWF, Aqua-AIRS, Other Satellite Retrievals • EDR Product Statistics. • Divakarla et al., “Preliminary Evaluation of NPP-CrIMSS EDRs with Heritage Algorithm (Aqua-AIRS) Retrievals, NASA-Sounder Team Meeting, Pasadena, CA, April 24-27, 2012. • Sample Maps Shown in this presentation. • Complete Set will be posted on NOAA FTP Site

  13. Improvements and Investigations Improvements • We are updating the CrIS/ATMS Tuning with CrIS/ATMS observations that will improve the Yield as well as the Retrieval Accuracy • We will update error covariance matrix associated with the radiance in the EDR algorithm to better represent the sensor noise and RTM related errors • Tweaking some of the pre-launch Thresholds • Investigations • Rejection of Polar Cases by both the ‘MW-only’ Stage and the IR+MW stage requires investigation. • Land/Sea Boundary rejections by MW-only Stage • Confusion of clear/overcast over the Polar Regions • Night time IR convergence is far better than Daytime IR convergence. What is causing the Daytime drop-out in QC needs to be investigated
