fond4Top-level expertise in atmospheric dispersion, meteorology and the development of urban air quality models, together with its mastery of maths and physics tools, place NUMTECH in a prime position to offer a broad panel of studies tailored to the diverse issues facing managers of industrial and institutional facilities. These studies are underpinned by an array of internationally recognized numerical modelling systems providing use of different spatio-temporal scales within a highly varied range of contexts and weather situations.

NUMTECH carries out global-scale missions ranging from research into the atmospheric dispersion of emissions linked to human activities, through to producing or forecasting air quality figures or providing expert assessments of meteorological events.

NUMTECH‘s work in designing and developing operational systems is driven by its expertise in atmospheric dispersion and meteorology, its skills in the use of mathematical, physics and modelling tools, and the experience gained by working in close collaboration with industrials and local environmental issues managers.

These systems, designed to analyse and monitor atmospheric discharges and air quality, are tailored to the specific needs of each individual entity, providing historic, real-time and forecast computations at extremely fine geographic scales.
They give decision-makers a means to deal with unforeseeable weather conditions, and to make plans and take measurements aimed at preserving environmental quality while ensuring minimal interference with economic activity. This forward planning can be used to optimise the financial management of regulatory compliance while curbing the risks of environmental accidents.
