WRF-Chem is the Weather Research and Forecasting (WRF) model coupled with Chemistry. The development of WRF-Chem is a collaborative effort among the community. NOAA/ESRL scientists are the leaders and caretakers of the code....

GEOS-Chem is a global 3-D model of atmospheric chemistry driven by meteorological input from the Goddard Earth Observing System (GEOS) of the NASA Global Modeling and Assimilation Office. It is applied by research groups around the world to a wide range of atmospheric composition problems. Scientific direction of the model is provided by the international GEOS-Chem Steering Committee and by Workin...

Fifth generation atmospheric general circulation model (ECHAM5) developed by Max Planck Insitute for Meteorology....

The Forum for Air quality Modeling (FAIRMODE) was launched in 2007 as a joint response initiative of the European Environment Agency (EEA) and the European Commission Joint Research Centre (JRC). The forum is currently chaired by the Joint Research Centre. Its aim is to bring together air quality modelers and users in order to promote and support the harmonized use of models by EU Member States, w...

Information on the origin of pollution is an essential element of air quality management that helps identify measures to control air pollution. In this document, we review the most widely used source-apportionment (SA) methods for air quality management. Using simple theoretical examples, we explain the differences between these methods and the circumstances where they give different results and t...

Building an effective air quality management system (AQMS) requires a process of continual improvement, and the source apportionment techniques described in this report can contribute in a cost effective manner to improving existing systems or even as the first step to begin an AQMS. This is good news for many developing country cities where the combination of rapid growth, dirty fuels, and old an...

The EMEP models have been instrumental to the development of air quality policies in Europe since the late 1970s, mainly through their support to the strategy work under the Convention on Long-range Transboundary Air Pollution. In the 1990s the EMEP models became also the reference tools for atmospheric dispersion calculations as input to the Integrated Assessment Modelling, which supports the dev...

This is a repository of data produced from the EMEP MSC-W model on the sulphur (S) and nitrogen (N), and air concentrations of ozone (O3) and particulate matter (PM). There is the yearly, monthly, daily, and hourly gridded NetCDF files available on EMEP 0.1º x 0.1º longitude-latitude grid EMEP_gridding_system_documentation, EMEP01 domain map) for the reported compounds from the met.no THREDDS data...

This data visualization tool supplements the EMEP MSC-W model and datasets. It shows the data on multiple pollutants (PM2.5, PM10, O3, SO4, SO2, NO2) concentration by country, sector, and observations (daily, monthly)....

EcoSense is a Europe-wide integrated atmospheric dispersion and exposure assessment model which calculates external costs related to the exposure to airborne pollutants with a focus on impacts on human health, following the Impact Pathway approach. To allow for a fast computation time, EcoSense uses so-called source-receptor matrices instead of a full atmospheric dispersion model. Source-receptor ...
