CEOS Instrument: Tropospheric Emission Spectrometer

Agency: NASA
Mission: Aura
Type:High-resolution nadir-scanning IR spectrometer
Description:3D profiles on a global scale of all infra-red active species from surface to lower stratosphere. Measures greenhouse gas concentrations, tropospheric ozone, acid rain precursors, gas exchange leading to stratospheric ozone depletion
Spatial Resolution: In limb mode: 2.3 km vertical resolution. In down-looking mode: 50 x 5 km (global), 5 x 0.5 km (local)
Swath Width: Limb mode: global: 50 x 180 km, local: 5 x 18 km
Wavebands: SWIR-TIR: 3.2 - 15.4 ?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.
