| One of CERCs
principle functions is to make use of new developments in environmental
research to develop practical but scientifically advanced environmental
software. Since its inception CERC, sometimes with sponsorship from
industrial companies and UK government departments, has produced numerous
models which tackle such issues as air dispersion, both planned and
emergency releases, air quality management, flow over complex terrain
and atmospheric emission data compilation including greenhouse gases.
Customization of standard release versions of our models
and the development of new software systems have been undertaken for
various clients who require specialised modelling packages. Our experience
covers a variety of applications, from fluid mechanics to database construction.
Examples include the development of FLOWPOR,
which models flow through porous structures (e.g. oil and gas rigs),
modification of ADMS to
calculate temperature and humidity fields in complex areas (e.g. heat
stress), ADMS Fire for
dispersion and deposition from fires and ADMSSTAR
for the assessment of short term accidental releases that are typically
radioactive. ADMSSTAR
includes an inverse calculation to estimate source strength from air
concentration or ground deposition samples.
If you would like to discuss a new
software system you would like produced or a customised application
of an existing CERC model, then please
contact us and our highly experienced development team will be pleased
to help.
Research
CERC undertakes a wide range of research projects broadly
covering atmospheric issues and complex flow problems. The projects
are varied and have been undertaken for local, national and international
organizations. They include many air quality studies comprising for
instance: mitigation scenario testing for both pollutant concentrations
and emissions; source apportionment; detailed studies of atmospheric
chemical mechanisms and dispersion in street canyons; scientific model
evaluation methodologies; development of the understanding and parameterizations
of boundary layer flows essential for improved dispersion modelling
including effects of complex topography, generation of coastal jets
and marine boundary layer structure.
Research projects currently being undertaken or recently
completed include the following:
PROMOTE
A project on air quality and UV forecasting at the European, National
and Local scales. The project is sponsored by the European Space Agency/Framework
6 Global Monitoring for the Environment and Security Programme (GMES).
The forecasts will make use of satellite and ground based measurements
and a range of models for different spatial scales. ADMS-Urban
is being used to provide high resolution local forecasts. For further
information see the GMES website, http://www.esa.int/esaLP/LPgmes.html.
TRAMAQ
As part of the DfT’s TRAMAQ research programme
(Traffic Management & Air Quality), we developed an emissions calculation
software tool for local authorities. The tool uses the latest data on
HGV emissions in urban areas under a variety of drive cycles to allow
users to take into account the impact of traffic management schemes
on vehicle emissions. It was piloted with local authorities in the spring
of 2004.
For further information see the DfT TRAMAQ web site.

Development of parameterisation
of the atmospheric boundary layer for offshore dispersion modeling.
Supported by the UK Department of Trade and Industry (DTI).
Developments of FLOWSTAR
for steeper terrain and coastal jets.
Supported by Kyoto University.
Dispersion of Accidental
Releases in Urban Areas
A review supported by the Atmospheric Dispersion Modelling Liaison Committee
(ADMLC), and available from the ADMLC
web site. It is intended to use this review as a basis for an enhanced
version of ADMS for terrorist
releases. This study has been referred to in the recent report by the
Royal Society: 'Making the UK safer: detecting and decontaminating chemical
and biological agents', available from this
link. The report recommends 'the proposed new centre should assess
the current and future capabilities of mathematical modelling to provide
real time information to inform first responders and emerging planners.'
SIGMEA
CERC is a partner is EU Framework 6 project with the goal of GMO mapping
across Europe. ADMS with
its advanced treatment of area sources is to be used for the dispersion
modelling aspects of the problem.
Dispersion of air pollution
in Urban Areas of the UK.
In this major study commissioned by DEFRA, modelling studies of air
quality in urban areas of the UK using ADMS-Urban
are being undertaken. The study includes future projections, source
apportionment, mitigation scenarios and also covers local dispersion
at airports. Documentation available to download
includes:
