Modelling of atmospheric radiation photochemistry and air transport

Following models are constructed and used now in research in the lab:

1. A photochemical box and 2D Gaussian Plume models for local processes in the aircraft or rocket exhaust plumes
2. 2D longitude-vertical diurnally and seasonally varying photochemical model in the 0-16 km layer of 30-60o N zonal belt is used in studies of zonal transport and photochemical transformations of atmospheric pollutants from the ground and elevated sources (such as aircraft emissions)
3. 2D latitude - vertical radiative, dynamical, photochemical seasonally varying fully interactive model of the zonally averaged 0-65 km global layer is used for analysing of the current and projected gas composition variations during the last glacial and interglacial periods with account of heterogeneous reactions on stratospheric sulfate aerosols and on polar stratospheric clouds
4. 3D Chemical Transport Model is constructed jointly with the Climate Research Group of the University of Illinois at Urbana-Champaign (US). An improved hybrid scheme for the 3-D air advection is used in 3D CTM
5. 3D Regional Transport Model driven by meteorological fields from ECMWF  is applied for estimations of methane sources in West Siberia and in large urban regions [see: publication]
   
6. 3D Global Chemistry Transport Model MEZON driven by UKMO assimilated data is used for evaluating of ozone distribution and trends
7. Trajectory model of air mass transport and photochemistry is constructed for describing of photochemical processes in Antarctic stratosphere polar vortex
