Vertical ozone distribution measured over Ny Ålesund (70ºN, 12ºE) inside the polar vortex

Fine structure in composition fields. Vertical ozone distribution measured over Ny Ålesund (70ºN, 12ºE) inside the polar vortex. [from www.nilu.no:80/projects/theseo2000]. Importance of modelling dynamics correctly. Modelled ClONO 2 fields - strong mixing results in less ClO to destroy ozone.

Presentation Transcript

  1. Fine structure in composition fields Vertical ozone distribution measured over Ny Ålesund (70ºN, 12ºE) inside the polar vortex [from www.nilu.no:80/projects/theseo2000]

  2. Importance of modelling dynamics correctly Modelled ClONO2 fields - strong mixing results in less ClO to destroy ozone [Figures from UGAMP]

  3. Gravity wave observations from CRISTA S.D.Eckermann & P.Preusse, Science, 286, 19 November 1999, 1534-1537.

  4. Gravity wave observations from CRISTA Predicted vertical wavelength (lz) theory versus measured(lz) over South America at 20-30 km in November 1998 [Eckermann, Science 286, 1999].

  5. Consistent vertical and horizontal resolution Vertical and horizontal resolutions for satellite sounders and numerical models [see Lindzen and Fox-Rabinovitz, Mon.Wea.Rev. 117, 2575-2583]

  6. Simulations of low and high horizontal resolution Simulation of N2O on the 2100 K isentropic surface from the SLIMCAT model (4 ppb contour interval). Below: gridded simulated ISAMS and HIRDLS observations for modelled field for a 12 hour window centred on the observation time. [Figure from Alan Iwi]
