The wind rose is a very useful way of summarising meteorological data. It is particularly useful for showing how wind speed and wind direction conditions vary by year. The windRose function can plot wind roses in a variety of ways: summarising all available wind speed and wind direction data, plotting individual wind roses by year, and also by month. The latter is useful for considering how meteor...

The trainings aimed to provide the young and early-career scientists from the local agencies, academic and research institutions, professional associations, and private sector with the opportunities to develop their knowledge and skills with respect to applying the PMF receptor model for PM2.5 source appointment and using MODIS AOD products for assessing biomass burning-related air pollution. The ...

PMF is a multivariate factor analysis tool that decomposes a matrix of speciated sample data into two matrices: factor contributions (G) and factor profiles (F). These factor profiles need to be interpreted by the user to identify the source types that may be contributing to the sample using measured source profile information, and emissions or discharge inventories. The method is reviewed briefly...

The State of Global Air 2024 reports provides a comprehensive analysis of data for air quality and health impacts for countries around the world in 2021....

Ground level ozone is a highly reactive, oxidative gas commonly found in urban and suburban environments, mostly derived from anthropogenic emissions. Numerous epidemiological studies and several reviews from health and environmental agencies worldwide have reported that exposure to this pollutant is associated with adverse health outcomes, including increased short term mortality and morbidity. E...

Assessing whether long-term exposure to air pollution increases the severity of COVID-19 health outcomes, including death, is an important public health objective. Limitations in COVID-19 data availability and quality remain obstacles to conducting conclusive studies on this topic. At present, publicly available COVID-19 outcome data for representative populations are available only as area-level ...

Background: Air pollution is a major environmental hazard to human health and a leading cause of morbidity for asthma worldwide. Objectives: To assess the current evidence on short-term effects (from several hours to 7 days) of exposure to ozone (O3), nitrogen dioxide (NO2), and sulfur dioxide (SO2) on asthma exacerbations, defined as emergency room visits (ERVs) and hospital admissions (HAs). Met...

This report presents the updated results of mortality and morbidity attributed to ambient air pollution (also known as ‘burden of disease due to air pollution’). It includes information on the sources of data on air pollution available to the WHO, on the methodology used to estimate human exposure to air pollution and related burden of disease, as well as the actual estimates of human exposure to ...

The report "Reducing Global Health Risks Through Mitigation of Short-Lived Climate Pollutants" highlights the significant impact of SLCPs like black carbon, methane, and ozone on both climate change and public health, attributing millions of premature deaths annually to air pollution. It emphasizes that mitigating SLCP emissions can yield substantial health benefits by reducing air pollution, impr...

The following technical report outlines the rationale, process and results of a joint research study, coordinated by the World Health Organization (WHO) and the Pan-American Health Organization (PAHO), co-chaired by the Ministry of Health and Social Protection and the Ministry of Environment and Sustainable Development in collaboration with the Climate and Climate Air Coalition, the Stockholm Envi...
