Tomorrow's talk: Measuring atmospheric composition: combining hardware and software to understand our changing atmosphere

[Elizabeth Patitsas]

Hi folks,

Tomorrow's talk will again take place in *Bahen 5256* (same room as
last week). Kimberly Strong from physics will be speaking on
"Measuring atmospheric composition: combining hardware and software to
understand our changing atmosphere"

Abstract: Spectroscopic techniques provide a powerful method for
measuring atmospheric composition. My research group uses UV-visible
and infrared spectrometers in Toronto and the Arctic for studies of
climate change, ozone depletion, and air quality. The retrieval of
trace gas abundances from the spectra recorded by these instruments
relies on sophisticated computer algorithms. In this talk, I will
describe how we acquire and analyze our measurements to derive
meaningful information about the atmosphere. I will also present some
results from the University of Toronto Atmospheric Observatory (TAO)
and the Polar Environment Atmospheric Research Laboratory (PEARL). For
the former, I will show how we interpret our measurements of
pollutants using a chemical transport model, while for PEARL, I will
discuss how we combine our measurements with atmospheric models to
quantify chemical ozone depletion.

See you tomorrow at BA 5256 at 3PM!

Cheers,
Elizabeth
