Europe's PM2.5 explorer

Sampled directly from the project rasters. Scrub time, inspect values, filter hotspots and zoom into regions.

Each circle represents one sampled raster location. Colour indicates annual PM2.5 concentration, or change when that mode is selected; circle size is fixed.

This map renders sampled PM2.5 values as interactive cells. Hover or click any cell to see its 2007 value, 2024 value and change.

The sampled layer is lighter than the full raster but much more interactive: it can be filtered, animated, styled and queried in the browser.
