 NPP
 JPSS-1
 JPSS-2
Status:Operational
Type:Medium-resolution IR spectrometer
Description:Daily measurements of vertical atmospheric distribution of temperature, moisture, and pressure
Spatial Resolution: IFOV 14 km diameter, 1 km vertical layer resolution
Swath Width: 2200 km
Wavebands: MWIR - TIR: 3.92 - 4.4 ?m, 5.7 - 8.62 ?m, 9.1 - 14.7 ?m, 1300 spectral channels
Technology: Medium-resolution IR spectrometer
Description: Spectrometer operating in MWIR and TIR with spectral resolution typically around 0.1 % to retrieve temperature and humidity profiles from absorption bands of CO2 and H2O in cloud-free or partially cloudy areas, and also total columns of some greenhouse gas species (and coarse profile of O3). Cross-nadir scanning for vertical profiling and total-columns. Many thousands of channels. Spatial resolution typically 10-20 km horizontal, ~ 1 km vertical (referred to the retrieved profile). Applicable in LEO and GEO.
