  1. DIRECT READOUT APPLICATIONS USING ATOVS ANTHONY L. REALE NOAA/NESDIS OFFICE OF RESEARCH AND APPLICATIONS

  2. AMSU AVHRR HIRS SARR POES (K-N`) Instruments • May 1998: The launch of NOAA-15 ushers in a new era in remote sensing… Courtesy of Paul Menzel

  3. NOAA POLAR OPERATIONAL SATELLITES • NOAA-15 (1930 LST; no AVHRR, no AMSU-A channels 11, 13) • NOAA-16 (1430 LST; AMSU-A Problems?) • NOAA-17 (2230 LST; Fully Functional)

  4. ATOVS ATMOSPHERIC RADIOMETER SOUNDERS • High-resolution Infrared Radiation Sounder (HIRS); 20-channels @17km…..Clouds, clear-sky Temperature, Moisture, and Surface • Advanced Microwave Sounding Unit-A (AMSU-A); 15-channels @50km…..All-sky Temperature, TPW, Cloud Water, and Surface • Advanced Microwave Sounding Unit-B (AMSU-B); 5-channels @16km…..All-sky Moisture, and Surface • Advanced Very High Resolution Radiometer (AVHRR); 6-channels @1.0 km (LAC), 4.0 km (GAC)……Clouds, clear-sky Surface

  5. POES Products Hurricane Floyd Fires at Los Alamos Input for forecast weather models 3-D measurements of temperature and humidity Cloud imagery Sea surface temperature observations Snow and ice cover Vegetation index Aerosol observations Atmospheric ozone measurements Fire detection and monitoring Volcanic ash cloud tracking Courtesy of Paul Menzel

  6. Satellite vs. NWP departure fields help focus attention on important mesoscale features • Products from ATOVS Courtesy of Tony Reale

  7. CLOUDS AND MOISTURE

  8. Fig 15

  9. NOAA-15 polar orbiting satellite 3 channel composite view of hurricane Bonnie the morning of August 25

  10. Hurricane Bonnie’s warm core revealed in temperature anomaly cross section derived using NOAA-15 Advanced Microwave Sounding Unit (AMSU) data

  11. Direct Readout

  12. DIRECT READOUT PROCESSING • MORE TIMELY • FULL DENSITY (ie, AVHRR “LAC”) • INDEPENDENCE • LOCAL INFLUENCES • FEEDBACK TO NESDIS

  13. ENVIRONMENTALSCIENCE APPLICATIONS • NUMERICAL WEATHER PREDICTION INITIALIZATION • ENVIRONMENTAL MONITORING • CLIMATE

  14. Ground Truth – Utilizing available RAOB Data Courtesy of Tony Reale

  15. Drought in South America Started in October 1999 and continues Most affected are Brazil, Paraguay, Argentina, and UruguayAVHRR data delineates areas of vegetation stress (Red areas)Data provided to USDA (Foreign Agriculture Service) Courtesy of Jim Purdom

  16. AMSU (blue) / GOES (dashed red) relative viewing geometry • AMSU Hurricane Intensity Estimation NOAA-15 AMSU-A T(C) 2332 UTC 11 Sep 99 GOES-8 IR 2315 UTC 11 Sep 99 “Hurricane Floyd” Courtesy of Paul Menzel

  17. POES/ NPOESS Users Science Teams Vendors Education and Training… • Building bridges — transferring knowledge between scientific, academic, and operational communities
