Polar Atmospheric Chemistry at the Tropopause
SCAR Action Group
Polar Atmospheric Chemistry at the Tropopause (PACT) aims to improve understanding of the distribution and variability of ozone in the polar upper troposphere – lower stratosphere (UTLS) region and the feedbacks of ozone changes to polar climate.
Recently PACT work as focussed on finalising a database on tropopause region parameters that is being derived using all available ozonesonde measurements poleward of 50° latitude. The ozonesonde data have been obtained from the World Ozone and Ultraviolet Radiation Data Centre (WOUDC; http://www.woudc.org/), the Network for the Detection of Atmospheric Composition Change (NDACC; http://www.ndsc.ncep.noaa.gov/sites/) and the National Oceanic and Atmospheric Administration’s Earth System Research Laboratory (http://www.esrl.noaa.gov/gmd/ozwv/ozsondes/index.html). The earliest data currently used are from Syowa in Antarctica (1966), although the majority of information comes from the 1990s and later years.
