National Centre for Climate Reseach - DMI

We here present the results of a study performed as part of the Danish National Centre for Climate Reseach.

The purpose of this study is a) to investigate methods for quantifying the volume,VPSC, from GNSS-RO stratospheric temperature and pressure data, and b) to investigate the long-term variability and trends of tratospheric temperatures conducive to the formation of PSCs. The objectives with these investigations are to further our understanding of role played by climate change for the evolution of ozone-depleting conditions in the Arctic, but also to lay the foundations for an operational service at DMI to monitor these conditions as they evolve day by day during the winter-spring seasons in the Arctic and Antarctic.

At present we present daily updated temperature measurements in the stratosphere and volume of PSC-forming areas over the polar regions. At a later stage additional results on PSC and vortex will be included.




This site is still in the development phase.
