Global 3D TOMCAT CTM tropospheric ozone simulations
Abstract
Global 3-D simulations of tropospheric ozone (TO3) from the TOMCAT chemical transport model (1996-2016) output at two satellite local solar overpass times (09.30 & 13.30 LST). The ozone data (2-daily overpass times) is provided as 3-D fields on the 2.8°×2.8° horizontal model grid. Atmospheric pressure (Pa) and temperature (K) have also included to provide vertical information on the ozone distribution up to 10 hPa. The ozone data has units of mass mixing ratio (1.0E-9). This work was undertaken primarily as long-term science activities of the NERC - National Centre for Earth Observation.

Process overview
| Title | TOMCAT model deployed on Leeds computer |
| Abstract | TOMCAT (and related SLIMCAT) is a global three-dimensional (3-D) off-line chemical transport model (CTM) which is developed and maintained at the University of Leeds. The model uses winds and temperatures from meteorological analyses (e.g. from the European Centre for Medium-Range Weather Forecasts) to specify the atmospheric transport and temperatures. The model then calculates the chemical composition of the troposphere and stratosphere based on the chemical scheme and inputs such as solar fluxes and trace gas emissions. The model has the option of detailed chemical scheme(s) for the stratosphere and troposphere and is the host model for the GLOMAP aerosol scheme. The model can be used to simulate the past and current atmosphere, to help interpret observations, and to diagnose the extent of environmental issues such as stratospheric ozone depletion or tropospheric pollution. INVICAT, the inverse version of TOMCAT, is used to derive surface emission fluxes. TCOM data products use machine learning to combine TOMCAT output and satellite observations. A number of datasets on CEDA have been produced with the TOMCAT model (and related SLIMCAT, INVICAT, TCOM). Further details of the specific model set-up are provided in dataset descriptions. |
