Summit, Greenland Balloon-Borne Ozonesonde Profile Measurment Program


Location:

Weekly balloon-borne ozone profiles are measured at The Greenland Environmental Observatory (GEOSummit, station code SUM) on the summit of the Greenland Ice Sheet: 72.6° North, 38.5° West: 3202 meters above sea level.

Date of Measurements:

February 12, 2005 – current.

Ozonesonde Measurement Campaign Participation:
  • ARCIONS: Arctic Intensive Ozonesonde Network Study
    Dates: 2008, April 1-21 & June 25 – July 12 (daily ozonesondes) A North American and Arctic ozonesonde network launched daily ozonesondes in the high-latitudes to look at springtime polar outflow and summertime boreal forest fire impacts on tropospheric ozone budgets.
  • MATCH: Determination of Stratospheric Polar Ozone Losses
    Dates: 2005-2008 (winter and early spring): The MATCH campaigns are coordinated by the Alfred Wegener Institute for Polar and Marine Research. 20-25 Arctic and high latitude sites launched ozonesondes at specific times during the spring to determine downwind chemical ozone loss in the stratosphere.

Background:

The GEOSummit site was established by the U.S. National Science Foundation (NSF) and the Danish Commission for Scientific Research in Greenland to provide year-round, long-term measurements for monitoring and investigations of the Arctic environment.

The facility is operated by CH2M HILL Polar Services (CPS) with guidance from the Science Coordination Office (SCO).
