  2. Integrated Product Validation System System Flowchart Cosmic ATOVS GOES AQUA Metop RAOB Model Truth Any or all of the data sets may be collocated using the information stored within the relational database. Collocated Locations Use locations to produce output data files NetCDF Collocated Data Files NetCDF files include both L1C and L2 products NRT Visualization and Monitoring Distribution

  4. Phase-1 Collocation Strategy • ATOVS reference soundings are collocated to radiosondes (first step) • Other satellite platforms are appended to the radiosonde-ATOVS reference collocations (second step) • Uncollocated radiosondes are retained and collocation with secondary observations attempted RAOB GOES 2 RAOB-Ref 1 Aqua Ref 3 Uncollocated RAOB COSMIC ?

  6. NOAA Integrated Sounding Product Validation System • ATOVS • Metop • NOAA-18 • MIRS • Metop • NOAA-18 PURPOSE: Centralized NOAA protocol for monitoring and validating operational satellite products IMMEDIATE GOALS: 1) Compile integrated multiple data platform datasets of collocated satellite and ground truth observations: ATOVS MIRS GOES Aqua-AIRS COSMIC ATOVS + IASI 2) Provide Analysis Radiosondes NWP Metop ATOVS (Eumetsat) ATOVS + IASI (NOAA) ATOVS + IASI (Eumetsat) Aqua-AIRS GOES COSMIC

  8. GOALS • Long-term record of multiple data platform (satellite and ground truth) collocated observations • historical (TOVS, DMSP … radiosonde (nwp)) • real-time (ATOVS, AIRS, IASI, GOES, COSMIC … radiosonde, NWP, GPS, ground radiometers…) • future (NPOESS / GOESR … ) • Unambiguous consistent validation of NOAA satellite sensor measurements and derived weather products • Monitoring and evaluation of ground truth platforms • Synergy with evolving NOAA instrument CAL/Val Programs … (insert NOAA Cal/val web site …..)

  9. Some Issues • Strategy for compiling (long-term ) Collocation database (support Climate) • Sonde Screening • Sonde not functioning as designed … (Reale / Tilley), IGRA (Durre), … • Non-homogeneity … Seidel, Lanzante, Haimberger … • Long term collocation record useful to characterize: • Sonde and sounder homogeneity record(s) • Homogeneity of calculated (from sonde using RTM) – obs radiance • Sensitivity of sounder measurement to sonde non-homogeneity • Sensitivity of sonde measurement to sounder non-homogeneity • Sounder sensitivity to weather signals • real-time weather scale • climate scale • RT development (resolving sonde and sounder measurements) • (reference networks synchronized to satellite overpass better) • Satellite derived product processing (tuning) and validation • Real-time (nwp) • Retrospective (climate) • Touching base with other collocated observations for climate (ERA-40 …) • Demonstrate “usefulness” of reference networks • Ground / satellite synchronization sensitivity studies (Seidel, Peterson, … GCOS)

  10. Research Topics • Radiosonde (Moisture ) Screening and Impacts • Raob Instrument Type Performance • Spatial / Temporal Sensitivity Studies (support GCOS Reference network initiatives) • Derived Product Integrated Validation • Derived Satellite Product Tuning and Research • RT Model Validation • Respective Platform Measurement / Product Uncertainty • Compiling Historical (from 1979) Collocation Data Records • (Historical) Radiometer Sensor Spectral Response Function Studies • Retrospective (historical) Satellite Processing for Climate
