Houghton Lecture - Tropical variability observed in GPS data

UTLS circulation and transport derived from satellite observations

The global upper troposphere - lower stratosphere (UTLS) is a transition region of strong dynamical and chemical variability, with contrasts in circulation and chemical behavior between the troposphere and stratosphere. This region exhibits complex dynamical, radiative, and chemical characteristics that place stringent requirements on observing and modeling systems. These lectures will focus on a series of topics related to the observed behavior of UTLS circulation, transport and chemical variability, as derived from satellite measurements combined with meteorological data sets.
