Dane pomiarowe ESA (Edukacyjna Sieć Antysmogowa)Measurement data from ESA (Educational Anti-Smog Network)
This dataset provides air quality measurement data collected as part of the ESA project, under which air quality meters are installed at schools in Poland. Depending on the configuration chosen, the sensors measure outdoor air quality near the school building on a continuous basis. Recorded parameters include outdoor concentrations of PM2.5 and PM10 particulate matter. The data is published as open data via Poland's national open-data portal and can be used for environmental monitoring, education, and research into local air pollution levels around schools.W ramach projektu ESA w szkołach instalowane są mierniki jakości powietrza. W zależności od wybranej konfiguracji oznaczana jest jakość powietrza na zewnątrz budynku szkoły. Mierzone są w trybie ciągłym następujące parametry: stężenie pyłu PM2,5 na zewnątrz szkoły; stężenie pyłu PM10 na zewnątrz...
