  1. Advanced Technology Microwave Sounder • ATMS provides high spatial resolution microwave data to support temperature and humidity sounding in cloud covered conditions. • Compared to AMSU (POES), ATMS (NPOESS) is one combined sensor with less total weight, power, and volume. • AMSU A+B => 160 kg, 200 W, 1 m3 • ATMS => 78 kg, 98 W, 0.2 m3

  2. ATMS Channel Set • 23.8, 31.4 GHz window channels • (precipitation, sfc , LWP, WVP, sea ice and snow cover) • 70 km (AMSU-A @ 50 km) • 54 GHz Oxygen band (13 channels) • temperature profiles • 33 km (AMSU-A @ 50 km, 1 less channel) • 88 GHz*, 165 GHz, and 183 GHz band (5) • water vapor profiles(and precipitation) • 18 km (AMSU-B, 2 less channels) • ATMS has contiguous pixels
