AB: EOS MLS is an instrument that remotely senses Earth's upper troposphere, stratosphere and mesosphere by measuring millimeter and submillimeter wavelength thermal emission from the atmospheric limb. It will be operated on the EOS Aura satellite starting in 2004, and is a follow-on to the MLS on the Upper Atmosphere Research Satellite. New technology enables many more measurements by EOS MLS than were possible with UARS MLS, and measurements to lower altitudes. The EOS MLS measurement suite includes H$_2$O, OH, HO$_2$, O$_3$, ClO, HCl, HOCl, BrO, N$_2$O, HNO$_3$, CO, HCN, CH$_3$CN, volcanic SO$_2$, temperature, cloud ice and geopotential height. All measurements are made day and night, simultaneously and continuously over 82S -82N latitudes on each orbit. Scientific objectives are to improve knowledge in areas of (1) stratospheric chemistry and chemistry-climate interactions, (2) upper tropospheric processes that affect climate variability, and (3) pollution in the upper troposphere. This talk will give an overview of the EOS MLS experiment.
