Introduction
CHABLIS is a major initiative to explore the atmospheric chemistry of the
Antarctic boundary layer (ABL) in greater detail and for a longer period of time
than has been achieved before.
Key Goals are:
- to explore the chemistry of the ABL 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;
- to test numerical models of the pristine atmosphere under extreme
conditions;
- to extend significantly our ability to interpret ice core data by
improving understanding of both the present-day atmosphere and transfer
functions.
Fieldwork was carried out at the new Clean Air Sector Laboratory at Halley
station . The team from UK universities and the British Antarctic Survey
brought to the project a suite of state-of-the-art instruments and models and
a track record of successfully running major campaigns together in remote
locations. The field campaign started during the austral summer in January 2004 and
continued throughout the winter culminating with an intensive study during the
summer of 04/05. 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.
CHABLIS was funded by a grant from the Natural Environment Research Council (NERC) Antarctic Funding Initiative (AFI).
