Instrument DescriptionMeasurement TechnologyTimeline
ACE-FTS
Atmospheric Chemistry Experiment (ACE) Fourier Transform Spectrometer
Operational
Measure and understand the chemical processes that control the distribution of ozone in the Earth's atmosphere, especially at high altitudes.Limb-scanning IR spectrometer
HiRDLS
High Resolution Dynamics Limb Sounder
Operational
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.Limb-scanning IR spectrometer
IASI
Infrared Atmospheric Sounding Interferometer
Operational
Measures tropospheric moisture and temperature, column integrated contents of ozone, carbon monoxide, methane, nitrous oxide and other minor gases which affect tropospheric chemistry. Also measures sea surface and land temperature.n/a
MLS (EOS-Aura)
Microwave Limb Sounder (EOS-Aura)
Operational
Measures lower stratospheric temperature and concentration of H2O, O3, ClO, HCl, OH, HNO3, N2O and SO2.Limb-scanning MW spectrometer
SMR
Submillimetre Radiometer
Operational
Measures global distributions of ozone and species of importance for ozone chemistry ClO, HNO3, H2O, N2O, (HO2, H2O2). Measures temperature in the height range 15 - 100 km.Limb-scanning MW spectrometer
TES
Tropospheric Emission Spectrometer
Operational
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.High-resolution nadir-scanning IR spectrometer
Microwave limb sounder (GACM)
Microwave limb sounder (GACM)
Proposed
