The Microwave Limb Sounder (MLS) experiments measure
naturally-occurring microwave thermal emission from the limb (edge) of
Earth's atmosphere to remotely sense vertical profiles of atmospheric
gases, temperature, pressure, and cloud ice. The overall objective of
these experiments is to provide information that will help improve our
understanding of Earth's atmosphere and global change.

The first MLS experiment in space (UARS MLS) was on NASA's Upper
Atmosphere Research Satellite (UARS) launched 12 Sept 1991.

The second (EOS MLS) is on the NASA Earth Observing System (EOS) Aura
mission launched 15 July 2004. EOS MLS began full-up atmospheric
science observations on 13 August 2004, with excellent performance to
date in all portions of the instrument. Provisional and Stage I
validataed data are now publicly available (for information go to EOS
MLS data).
