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
