The authors have employed a ground-based, cryogenically cooled tunable heterodyne spectrometer operated near 275 GHz to make frequent quantitative measurements of various trace gases at the Amundsen-Scott South Pole Station over an 11 month period. An overview of the data collected by this system for O3, N2O, NO2, HNO3, and ClO in the polar vortex. Vertical profiles of the chosen trace gases are affected by the gas phase chemistry, heterogeneous chemistry on particle surfaces, condensation, photochemistry, and transport. A unique record has been obtained from which the dynamical development of the Antarctic winter vortex can be obtained.
