Measurements and Applications
|
Measures profiles of atmospheric temperature, humidity, ozone, carbon monoxide, columns of methane, nitrous oxide, and other minor gases, and sea, ice, and land surface temperature and emissivity. Provides information on aeorols and cloud: fractional coverage, phase, cloud top height (input to Polar AMVs) and particle size. Prime applications: NWP, AC/AQ, climate. Secondary applications: NWC, land/ocean surface monitoring. IASI-NG will resume IASI role as internationl standard for satellite inter-calibration (GSICS).
