Open environmental data,
collected in the field.
We publish air quality, water and soil measurements gathered by volunteers and small research groups, together with the methods used to collect them.
Air
Urban air quality
PM2.5 and NO₂ readings from low-cost sensors, calibrated against reference stations.
Water
River monitoring
Monthly samples: temperature, pH, dissolved oxygen and conductivity.
Soil
Soil health survey
Organic matter and moisture profiles across agricultural and urban plots.
Latest updates
October dataset for river monitoring is now available on the data page. Sensor calibration notes were revised for the winter season.
