Overview
- Monitoring stations report recent exceedances of daily PM2.5 and PM10 thresholds in multiple cities, including repeated PM2.5 breaches in Hannover and several PM10 over-limit days this year in Görlitz and Niesky.
- Forecasters say snow or rain and an eventual shift to westerly winds should gradually improve air quality in the coming days, though timing and local effects may vary.
- Health agencies warn that elevated fine particulates increase respiratory and cardiovascular risks, and they advise sensitive groups to limit strenuous outdoor activity.
- Authorities attribute the episode to a mix of local emissions from traffic, agriculture and residential wood‑burning, alongside a transboundary plume from Poland and Czechia that officials cannot precisely quantify.
- Officials note that some apps show harsher readings because they use models, satellite data or low‑cost sensors, whereas the government index is based on calibrated state monitoring stations.
