| Technology: | Narrow-band channel IR radiometer |
| Description: | Radiometer operating in MWIR and TIR with many channels of bandwidth around 1 % in absorption bands of CO2 and H2O to retrieve temperature and humidity profiles in cloud-free or partially cloudy areas. Cross-nadir scanning for vertical profiling. A few tens of channels. Spatial resolution typically 10-20 km horizontal, ~ 2 km vertical (referred to the retrieved profile). Applicable in LEO and GEO. |
