The EOS Aura Microwave Limb Sounder (EOS MLS)

EOS MLS, on NASA's Aura satellite launched 15 July 2004, remotely senses Earth's upper troposphere, stratosphere and mesosphere by measuring millimeter and submillimeter wavelength thermal emission from the atmospheric limb. It is a follow-on to the Upper Atmosphere Research Satellite (UARS) MLS launched in 1991. The measurement suite for which EOS MLS was designed includes OH, HO2, H2O, O3, HCl, ClO, HOCl, BrO, N2O, HNO3, CO, HCN, temperature and cloud ice. Early results have demonstrated these measurements over an initial altitude range. This talk will give an overview of EOS MLS and some early results from it.
