noaa polar operational satellites
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)
atovs atmospheric radiometer sounders
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

direct readout processing
DIRECT READOUT PROCESSING
  • MORE TIMELY
  • FULL DENSITY (ie, AVHRR “LAC”)
  • INDEPENDENCE
  • LOCAL INFLUENCES
  • FEEDBACK TO NESDIS
environmental science applications
ENVIRONMENTALSCIENCE APPLICATIONS
  • NUMERICAL WEATHER PREDICTION INITIALIZATION
  • ENVIRONMENTAL MONITORING
  • CLIMATE

Drought in South America

Started in October 1999 and continues

Most affected are Brazil, Paraguay, Argentina,

and UruguayAVHRR data delineates areas of vegetation stress
