Scientific objectives

From Polstracc

Mission objectives of POLSTRACC are ...

  • To monitor in a changing climate the spatial and temporal variability of trace constituents, incl. aerosols, in the lowermost stratosphere during several phases of the polar winter ; assess trace gas budgets etc.
  • To provide global models with accurate data from the deployments to refine their algorithms; to investigate whether the models can reproduce the spatial an temporal changes on ozone and relevant trace gases
  • To complement in a synergetic way satellite observations with dedicated field measurements
  • To better understand changes in the ozone layer in a changing climate (subject of several HALO, national and EU initiatives)
  • To improve the predictive capabilities on the development of the ozone layer in the coming 50 years
  • To test precursors for future satellite experiments
