Model Results for Winter 2011/2012

This page contains preliminary results from simulations with the SLIMCAT 3D model chemical transport model. The near real time model run is forced by ECMWF T42L91 operational analyses with a horizontal resolution of 2.8 x 2.8 degrees and 32 levels from the surface to ~60 km.

This work is supported by the NERC National Centre for Earth Observation (NCEO) and National Centre for Atmospheric Science (NCAS).

Preliminary Model Results

This page contains recent, preliminary SLIMCAT model results for winter 2011/2012. Contact Prof. Martyn Chipperfield and Dr. Wuhu Feng for more details and requests.

Here is an animation of O3 loss (left) and ClOx (right) at ~470K during winter 2011/12.

Figures (460K) and (column o3 loss) show time series of vortex-averaged chemical ozone loss at ~460 K and summed over the partial LS (380-550 K) column for Arctic winters 1994/95 to 2011/12. For more information, please see Feng et al., Large Chemical Ozone Loss in 2004/05 Arctic Winter/Spring, Geophys. Res. Lett., 34, L09803, doi:10.1029/2006GL029098, 2007.

The corresonding ps files are available at ps files to download.

SLIMCAT output at pressure levels are available at netcdf format to download.
