Zusammenfassung |
Balloon-borne measurements of CFC11 (from the DIRAC in situ gas chromatograph
and the DESCARTES grab sampler), ClO and O3 were made during the
1999/2000 Arctic winter as part of the SOLVE-THESEO 2000 campaign, based in
Kiruna (Sweden). Here we present the CFC11 data from nine flights and
compare them first with data from other instruments which flew during the
campaign and then with the vertical distributions calculated by the SLIMCAT
3D CTM. We calculate ozone loss inside the Arctic vortex between late
January and early March using the relation between CFC11 and O3
measured on the flights. The peak ozone loss (~1200ppbv) occurs in
the 440-470K region in early March in reasonable agreement with other
published empirical estimates. There is also a good agreement between ozone
losses derived from three balloon tracer data sets used here. The magnitude
and vertical distribution of the loss derived from the measurements is in
good agreement with the loss calculated from SLIMCAT over Kiruna for the
same days. |
