We are experts in air pollution modeling. In more than 20 years of activity, we have made hundreds of studies
worldwide, mainly using the US EPA preferred models AERMOD and CALPUFF,
to assess the air quality and odor impact of industrial stacks and fugitive
emissions, traffic, construction sites, flares, cooling towers, offshore
platforms, landfills, waste incinerators, ships, trains, airports.
We help professionals and companies in preparing the technical documentation on modeling for compliance and permitting. Also, we provide scientific support in litigation, on air dispersion modeling and atmospheric-related issues, together with our US partner EnviroComp Consulting, Inc.
We offer a spectrum of services which range from the meteorological characterization of a site in a specific period of time (e.g. trends of precipitation, temperature, relative humidity, mixing height, plots of wind roses, plots of stability roses) to the preparation of the meteorological input for atmospheric dispersion models as AERMOD and the geographical and meteorological input of three-dimensional models as CALMET. We also run WRF on specific domains and prepare the input for CALMET through CALWRF (3d.dat files), or directly for AERMOD and CALPUFF through MMIF.Order meteorological data
We develop and distribute Windows applications for air quality, meteorology and safety, including WindRose PRO 3, for analyzing and plotting directional data, FLARES, for dimensioning industrial flares and estimating their emissions and impacts (thermal and acoustical), WRF Browser, for visualizing and exporting in KML format the output of the meteorological model WRF.
We also write ad-hoc programs in different languages (Perl, Fortran, VB.NET, IDL, GNUplot) for different operating systems. We have deep experience in processing very large datasets of complex structure and produce statistical analyses and georeferenced representations in several formats, including shapefiles and KML files.
We develop computer models for air quality modeling. They include LAPMOD (Lagrangian
particle model coupled with the meteorological model CALMET), WetPlume
(numerical model for plume water content dispersion and deposition), TOXFLAM
(short term analytical dispersion model), APOLLO2 (Long-range Lagrangian
All our models are referenced by publications on international scientific journals.
LAPMOD is available for download, for free.
We develop modern web-based platforms with client-server architecture for the online application and evaluation
of air quality models. They include AQWEB (ARPAE, Italy), for using from
remote the LAPMOD model; ENSEMBLE (European Commission JRC), for the
evaluation of air quality models and for early warning in case of nuclear emergenices; ARIES (I.S.P.R.A. Rome), the official
Italian system for real-time simulation of nuclear releases in air; TM5-FASST
web interface (European Commission JRC) to evaluate how air pollutant emissions
affect large-scale concentrations and their impact on human health and
We participate to international projects and we have published more than 100 papers on international peer-reviewed
journals and conferences proceedings.
Our many clients worldwide range from professionals and small consulting companies to international agencies, universities and global corporations. More...
