Particulate Matter (PM2.5) Concentrations in Lisbon

Overview This feature service provides spatial data on concentrations of particulate matter with a diameter less than 2.5 micrometers (PM2.5), which is a critical air pollutant affecting human health and the environment. The data represent measurements of PM2.5 levels within a specific geographic region around Lisbon, Portugal. Feature Layers Particulate Matter (PM2.5): This layer presents detailed particulate matter concentration data at a fine grid level. The data includes PM2.5 concentration values and geometric attributes describing the spatial extent and shape of each grid cell, which allows for detailed mapping and analysis of air quality patterns. Geographic Coverage The dataset covers an area in and around Lisbon, Portugal. It includes spatial measurements confined within this metropolitan region allowing localized analysis of air pollution levels. Use Cases Environmental monitoring and assessment of air quality impacts on public health. Urban planning and policy-making to mitigate air pollution exposure in populated areas. Research on spatial distribution and sources of fine particulate matter in urban environments. Integration with other geographic information systems (GIS) for further environmental and health impact studies. Data Source and Accessibility The data is provided and maintained by the Institute of Geography and Spatial Planning of the University of Lisbon (IGOT).
