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
