Meteosim was founded in 2003 as a spin-off from the alliance between researchers from the Department of Astronomy and Meteorology of the Faculty of Physics at the University of Barcelona (Spain) and the American company Meso Inc. (New York), which enjoys worldwide recognition in the field of meteorology.

Meteosim focused their activity on:  


 We provide air quality solutions based on numerical models:

 Meteorological data for running dispersions models (AERMOD, CALPUFF, ADMS, CMAQ)

  • Cloud user-friendly platform for running AERMOD and CALPUFF.
  • Environmental Impact Assessment Studies for energy, oil&gas, mining and industrial sector.
  • Air quality strategic consulting service for public administration (improvements plans, transport analysis, etc.)
  • Air quality forecasting system for mining companies, power plants, oil& gas companies, ports and regions.
  • Model expertise: Weather Reaseach Forecasing (WRF), AERMOD, CALPUFF, CMAQ, WRF-Chem, Hysplit, Aloha 


Climate studies and services, to enable strategic decisions to be made in the context of adaptation plans and climate resilience for cities, large infrastructures, coastal areas, sectors of economic activity and ecosystems.

Experts in downscaling technics that allows to evaluate the local impact of the climate change. We are working with dynamical and statistical downscaling.


We provide solutions for effective decision-making to manage weather hazards (fires, extreme wind, heavy precipitation or swell) and industrial risks (chemical emergencies, HAZOP, Seveso), taking into account national and international regulatory frameworks. 

We are working for main oil&gas companies and public administration. 

Model expertise: Weather Reaseach Forecasing (WRF), Hysplit, Aloha


We have more than 20 years of experience in the implementation of

mesoscale and microscale weather simulation models for in world wide

for a different economic activities (insurance, agriculture, media, risk,


We are also helping Official Meteorological Agencies to update its

numerical weather prediction infrastructure and own knowledge. 

Model expertise: Weather Reaseach Forecasing (WRF)


We provide weather, wave, swell and current forecast for companies with offshore activity. We also perform consultancy studies for determining metocean conditions for offshore and nearshore projects, hind cast, down-time periods, metocean climate extreme analysis, etc. 

 Model expertise: Weather Reaseach Forecasing (WRF), Wave Watch 3 (WW3), SWAN, HYCOM, Genome.


We are committed to permanently seeking innovative solutions for society at large.



Air Quality

We specialise in the preparation of studies and the development of tools for the forecasting and diagnosis of air quality. This technology, which is compulsory and essential for obtaining environmental licenses, enables us to analyse and implement mitigation and reduction strategies for the impact of atmospheric pollution, through the simulation of dispersion processes for pollutants produced by one or more emission sources.

Meteosim’s extensive know-how in the field of air quality and meteorology has made it a leader in the industry, which provides services worldwide to public authorities and private companies.

We offer our clients the latest atmospheric pollution modelling tools and services which best adapt to each project, with the aim of improving the environmental management of their processes, reducing associated costs (fines, downtime, etc.) and thereby improving their results.


Climate Change

In recent years, the needs of engineering and consulting services with regard to issues of climate change have grown considerably, in particular in the public sector, but also, increasingly, in the private sector.

Our focus has been on aspects of adaptation and we provide a very high level of specialisation which makes us stand out from the crowd in the preparation of high quality regionalised climate scenarios, enabling decision-making in very specific areas and sectors.

Climate change is a global phenomenon, but its impact is seen locally. Therefore, having regional future scenarios is essential so as to enable the correct design of adaptation plans both for countries (especially developing countries) and for regions, cities and economic sectors.

Our experience in climate resilience covers areas such as water resources, transport infrastructure (roads, bridges, ports, etc.) and a whole range of economic activities.


Risk Management

We develop early warning systems (EWS) and solutions to respond to various problems related to risks and emergencies, in order to support the decision-making process.

Our approach is based on the combination of high horizontal resolution, numerical weather forecasting models, with specific risk simulation models.

This enables risk situations to be detected and early warnings to be given, and allows for the optimisation of the allocation of resources in response to emergencies.

In addition, our risk management solutions incorporate a risk map display module that is designed in such a way as to facilitate quick decision-making by the people in charge of public and private emergency control centres.


Applied Meteorology

We have developed a comprehensive methodology to adapt meteorological models to each geographical area, by striving for the optimal physical configuration, improving the physiographic databases (uses of land, topography, etc.), and integrating observational data. All of these aspects have a significant impact on the modelling results.

The domain of the mesoscale meteorological modelling tools and the existence of a proprietary high performance computing system, enables us to provide a wide range of operational services.

We have various solutions aimed at different industries which all use meteorological and/or metocean simulation models.

The various solutions are designed and created in a specific and customised way for each of our customers (the media, mobile applications, insurance and reinsurance companies, experts, ski resorts, etc.).


Metocean Services

Meteorological and oceanographic phenomena can significantly affect the smooth running and management of marine and coastal activities, and can have a negative impact on the safety and cost of these activities and the environment in which they take place.

Meteorological and marine modelling systems enable any potential risks to which a specific maritime activity may be exposed to be diagnosed. These methodologies enable exposure to the aforementioned potential impacts to be assessed and quantified.

We specialise in the preparation of climate studies and marine forecasting tools which support the different phases of a project or operation (design, construction and exploitation) and provide a detailed diagnosis of the environmental conditions in the area of activity.

These tools also lead to optimisation in the design of infrastructure (lower costs) and aid the decision-making process, thus preventing the exposure of infrastructure and workers to risk situations.


Research and Development

Meteosim is an innovative SME which is committed to environmental, technological and economic progress in our society. Since the founding of Meteosim in 2003, there has been a permanent commitment to technological and service innovation throughout the company. In addition, Meteosim has an R&D&I department which actively works on the preparation of projects in the fields of climate change, air quality, weather forecasting, metocean analysis and the management of risks associated with extreme events.

In particular, at Meteosim, we have shown commitment to the development of climate services that facilitate the design of strategies of adaptation to climate change in key sectors of society, such as agriculture, water and energy management and the construction of infrastructure.

Since 2010, Meteosim has participated in numerous R&D&I projects financed by the European Union through the FP7 and Horizon2020 framework programmes.
