1. CALIBRATION AND RE-PROCESSING STATUS Calibration Status –VIS will be completed in September –IR will be completed in October –Microwave ready back to 98, earlier ??? Re-processing Sequence: Ancillary will be completed in September ISCCP/GPCP will start in November SRB will start in January SeaFlux & LandFlux will start in March

2. VIS CAL Evaluation Summary AVHRR vs MODIS & NOAA Cal ISCCP Biased LOW by ≤ 3%, RMS ≤ 4% (Except NOAA-17 at 8% & 9%) Afternoon Satellites Generally Agree Some Degradation Trends Need to be Adjusted (NOAA-7 & 17 but NOT NOAA-9 or 18) Some Re-evaluations of Degradation Record (Especially Morning Satellites, NOAA-10 & 12)

3. COMPARISONS TO NOAA-9 and NOAA-18

4. RE-EVALUATIONS

6. VIS CAL Evaluation Summary MODIS-DCC Calibration of 12 Geos – Gain ISCCP Biased LOW by 2-4%, RMS 2-4% ISCCP Results Noisier than Doelling Results A Few Degradation Trend Differences Some “Local” Discrepancies

7. VIS CAL Evaluation Summary Overall Evaluation of Accuracy: About 3% “ABSOLUTE” BUT What is Uncertainty of Moon? What is Uncertainty of MODIS? What is Uncertainty of Earth Targets?

8. Common Data Format 1 Degree Equal-Area Mapping (0,0 is corner) 3 hr  1 day Time intervals (lowest common?) –(month/year) file names Binary – Byte Coding –reserved missing data code Fixed Variable Arrays Area statistics and joint histograms netCDF4 format

10. ISCCP Status Overview Processing –D-Version Completed: July 1983 – December 2009 (26.5 yr) –B1 Deliveries up to date –Calibration Finished thru December 2009 (SCC ends 2011) Revisions –Cloud Detection Algorithm Finished for B1U w polar revision –Cloud Retrieval Revisions Finished (still testing) except for aerosols & land reflectance Re-engineering –Code Modernized, Adapted to B1U/GAC & Ported –NCDC has run complete version –Still have to Revise Ancillary Inputs –New Products (H-Version) Designed

11. VIS Monitor PM Orbiters MODIS POINT Estimated Relative Uncertainty

12. FINAL ISCCP D-VERSION CLIMATOLOGY CA = 66.3%TAU = 3.9 PC = 572 mb TC = 261.6K

13. FINAL ISCCP D-VERSION CLIMATOLOGY TS = 288.7KRS = 0.14

14. NEW DATA PRODUCTS B1U Radiances ANCILLARY: Lnd/Wtr Mask & Topography, Landcover, Ozone, Merged Snow-Ice, Atmospheric Temperature & Humidity HXS: high-res, pixel (10 km), single-satellite (like old DX) HXG: high-res, pixel, global (global-DX reduced to common variables, in netCDF) All gridded products in netCDF HGS: high-res, gridded (1°), single-satellite (DS-plus) HGG: high-res, gridded, global (like old D1, merged DS) HGH: high-res, gridded, hourly-monthly mean (like old D2) HGM: high-res, gridded, monthly-mean (like old D3) FH Radiative Flux Products (INPUT, PROF, TOA, SRF, MON)

15. Remaining Tasks & Re-Processing Plan IR calibration and/or revise spectral treatment Testing whole system Reviewing whole record for small glitches -- QC development Re-processing plan: –Start with 2009 incorporating FY-2C/E –Re-process in reverse chronological order –Process 2010 incorporating Brazil-GOES as soon as Calibration Ready –Finish whole record adding 2011 Replace/revise VIS calibration procedures – after start

17. JOINT PRODUCT DESIGN & SUGGESTED USES Joint Product Design (List Contents -- Handout) Suggested Uses –Characterize Exchanges (and imbalances) for Forced Variability (diurnal, seasonal) Weather-scale Variability (aka Internal Modes, convective, baroclinic) Slow modes (MJO, interannual, ENSO, etc) –Generation of APE –E&W Transports & their Variations –Exchange Process Studies

19. POLAR PRIORITIES Sea Ice Surface Temperature Better Atmospheric Temperature Profiles Precipitation Cloud Vertical Structure

21. SUGGESTED MODEL DIAGNOSTICS Distributions of diabatic heating Composite Weather State Variation Statistics Forced Modes: Amplitude & Phase Internal Modes: Variance with Space-Time Scales Slow Modes: Frequencies of Occurrence, Geographic Patterns, Amplitude Distributions
