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
• 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
• MORE TIMELY• FULL DENSITY (ie, AVHRR “LAC”) • INDEPENDENCE• LOCAL INFLUENCES
• FEEDBACK TO NESDIS
ENVIRONMENTAL SCIENCE APPLICATIONS
• NUMERICAL WEATHER PREDICTION INITIALIZATION
• ENVIRONMENTAL MONITORING
• CLIMATE
• Ground Truth – Utilizing available RAOB Data• Ground Truth – Utilizing available RAOB Data

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