Using Observations for Model Evaluation
Verification and diagnostic activities are critical for the success of both numerical weather prediction and weather forecasting efforts at organizations around the world. There are several concerns that should be addressed before starting a model evaluation activity, including understanding the nature of observations that will be used for the evaluation. This information will determine what...
The Atmosphere Monitoring Service of the European Copernicus Programme (CAMS) is an operational service providing analyses, reanalyses and daily forecasts of aerosols, reactive gases and greenhouse gases on a global scale, and air quality forecasts and reanalyses on a regional scale. In CAMS, data assimilation techniques are applied to provide daily analyses using remote sensing and in-situ...
In order for an air quality model to better emulate and represent the atmospheric pollution in a region, its performance has to be evaluated to both identify uncertainties and reproduce ambient observations.
An air quality modeling system has been implemented at UNAM’s Institute of Atmospheric Sciences and Climate Change with the main objective of generating air quality forecasts for the area...
Wildfires are important emission sources that generate large amounts of aerosols into the atmosphere. These hazardous events have been increasing rapidly due to the climate change effects, leading to poor air quality, which causes impacts on the society, including adverse health effects, life and property losses, and the economic burden. To mitigate these effects, many regional and global...
Three agencies that produce daily operational air quality forecasts for North America began to exchange their forecasts on a routine basis in 2017, allowing a side-by-side comparison and ongoing evaluation of four different forecasts. The three agencies were Environment and Climate Change Canada (ECCC), which produces two slightly different forecasts, the U.S. National Oceanic and Atmospheric...
