“CHABLIS”

Chemistry of the Antarctic Boundary Layer and the Interface with Snow


Aims of this meeting
Aims of this meeting:

  • To remind ourselves what CHABLIS is all about!

  • To pick up the thread and re-focus ourselves…


Chablis history ie how we got where we are today
CHABLIS History(ie. how we got where we are today)

  • Idea “born” post Neumayer season (1999)

  • University groups approached (Leeds, UEA, Bristol, IC)

  • Proposal submitted December 2000; funding announced May 2001

  • CHABLIS commenced Oct 2001

  • 2001/02 E.S. Shackleton didn’t arrive at Halley

  • Field work component delayed 1 year


Three research foci
Three research foci:

  • Seasonal studies of oxidant chemistry in coastal Antarctica:

    • What is the annual climatology of radical precursors in the Antarctic troposphere?

    • Is there evidence for radical chemistry during the Antarctic winter period?

    • Can we balance the budget of tropospheric O3 during spring/summer?


Three research foci1
Three research foci…

2. Year round studies of the NOy budget in coastal Antarctica:

  • What controls the NOy budget throughout the year?

  • How does this affect tropospheric NOx and ice core nitrate?


Three research foci2
Three research foci…

3. Air/snow exchange mechanisms of trace gases :

  • What is the connection between snow and the boundary layer concentrations of key species?

  • What is driving the firn air profiles of halocarbons and alkyl nitrates?





The timescale
The Timescale

  • Phase 1: Summer 2003/04: Initial studies and install overwintering instruments

  • Phase 2: Winter 2004: Overwinter studies (NOy budget, air/snow exchange)

  • Phase 3: Summer 2004/05: Summer intensive (focus on oxidants)
