Atmospheric composition forecasting in Europe

Atmospheric composition forecasting in Europe

The atmospheric composition is a societal issue and, following new European directives, its forecast is now recommended to quantify the air quality. It concerns both gaseous and particles species, identified as potential problems for health. In Europe, numerical systems providing daily air quality forecasts are numerous and, mostly, operated by universities. Following recent European research p...

Forecasting global atmospheric CO2

A new global atmospheric carbon dioxide (CO2) real-time forecast is now available as part of the preoperational Monitoring of Atmospheric Composition and Climate – Interim Implementation (MACC-II) service using the infrastructure of the European Centre for MediumRange Weather Forecasts (ECMWF) Integrated Forecasting System (IFS). One of the strengths of the CO2 forecasting system is that the la...

Atmospheric Structure and Composition,

Atmospheric Composition, Chemistry, and Clouds

Venus’ atmosphere has a rich chemistry involving interactions among sulfur, chlorine, nitrogen, hydrogen, and oxygen radicals. The chemical regimes in the atmosphere range from ion-neutral reactions in the ionosphere to photochemistry in the middle atmosphere to thermal equilibrium chemistry and surface-atmosphere reactions in the lower atmosphere. This variety makes Venus an important planet t...

Forecasting Human Exposure to Atmospheric Pollutants in Portugal

Air pollution has become one main environmental concern because of its known impact on human health. Aiming to inform the population about the air they are breathing several air quality modelling systems have been developed and tested allowing, nowadays, assessing and forecasting air pollution ambient levels in many countries. However, every day, one individual is exposed to different concentra...
