CEOS Instrument: High Resolution Dynamics Limb Sounder

Agencies: NASA [Primary]
Mission: Aura
Status:No longer operational
Type:Limb-scanning IR spectrometer
Description:Measures atmospheric temperature, concentrations of ozone, water vapour, methane, NOx, N2O, CFCs and other minor species, aerosol concentration, location of polar stratospheric clouds and cloud tops. Currently not collecting data on Aqua.
Spatial Resolution: Vertical: 1 km, Horizontal: 10 km
Swath Width: N/A
Wavebands: TIR: 6.12 - 17.76 ?m (21 channels)
Technology: Limb-scanning IR spectrometer
Description: Spectrometer operating in MWIR and TIR with spectral resolution typically around 0.01 % required for atmospheric chemistry. Designed to provide high vertical resolution in the upper troposphere and above by scanning the Earth’s limb. Many thousands of channels. Spatial resolution typically 1-3 km vertical, 300-500 km horizontal. Applicable only in LEO.
