CHABLIS
Chemistry of the Antarctic Boundary Layer and the Interface with Snow
CHABLIS is a major initiative to explore the atmospheric chemistry of the coastal Antarctic boundary layer in far greater
detail and for a longer period of time than has been achieved hitherto.
Conducted at the Clean Air Sector Laboratory (CASLab) British Antarctic Research Station, Halley, a year-round study of chemical climatology, starting in January 2004, culminated in an intensive summer
campaign in January-February 2005 where a comprehensive suite of radicals and other trace species was measured. Major foci
for CHABLIS included detailed studies of seasonal oxidant chemistry, annual variation in the boundary layer NOy budget,
and elucidating air/snow transfer processes.
The Key CHABLIS Goals:
1. to explore the chemistry of the Antarctic Boundary Layer through a year-round study of chemical climatology culminating in an intensive summer campaign to measure a comprehensive suite of radicals and other trace species;
2. to test numerical models of the pristine atmosphere under extreme conditions;
3. to extend significantly our ability to interpret ice core data by improving understanding of both the present-day atmosphere and transfer functions.
