  10. Advanced Technology Microwave Sounder (ATMS) • In conjunction with CrIS, daily global observation of atmospheric temperature and humidity profiles • Multi-channel scanning microwave total power radiometer • 2300 km swath, 66 Kg, 0.3 Kbps avg.

  11. Cross-Track Infrared Sounder (CrIS) • In conjunction with ATMS, daily global observation of atmospheric temperature and humidity profiles • Michelson interferometer infrared sounder covering 3.5 – 16 mm • 2300 km swath, 81 Kg, 1.5 Mbps avg.

  12. Visible/Infrared Imager/Radiometer Suite (VIIRS) • Daily global observation of land, oceans, and atmosphere for climate research and weather forecasting • Multispectral (visible through thermal infrared) scanning radiometer • 3000 km swath, 200 Kg, 8 Mbps avg.

  13. Conclusion • Proceeding with Mission Formulation • Offers benefits to research and operational communities • Calibrated, geo-located, global observations for research after EOS Terra and PM • Incorporate lessons-learned from EOS Terra and PM into NPP in the areas of instruments, calibration, validation, spacecraft, and ground processing • A key benefit to operational community is early evaluation of NPOESS-like data • Allows for the calibration/validation of sensors & algorithms • Facilitates the transition to using NPOESS data • Website: http://jointmission.gsfc.nasa.gov
