Instrument:IRS
Agencies: CAST [Primary]
 INPE
Missions: CBERS-3
 CBERS-4
Status:Prototype
Type:High-resolution nadir-scanning IR spectrometer
Description:Used for fire detection, fire extent and temperature measurement
Spatial Resolution: PAN, SWIR: 40 m, TIR: 80 m
Swath Width: 120 km
Wavebands: 0.5 - 0.9 ?m; 1.55 - 1.75 ?m, 2.08 - 2.35 ?m; 10.4 - 12.5 ?m
Technology: High-resolution nadir-scanning IR spectrometer
Description: Spectrometer operating in MWIR and TIR with spectral resolution typically around 0.01 % required for atmospheric chemistry. Earth viewing so as to measure vertical profiles and total columns in cloud-free or partially cloudy areas. Cross-nadir scanning for vertical profiling and total-columns. Many thousands of channels. Spatial resolution typically 5-10 km horizontal, ~ 1 km vertical (referred to the retrieved profiles). Applicable only in LEO.
