Proboštov, November 10, 2026: daily mean PM2.5 23 µg/m³ (4 sensors), level “Moderate” — as in the Atmy Data Hub. Open methodology and data in JSON: Methodology and data sources · JSON

There are not enough fresh measurements for Proboštov right now. From 10:00 to 20:00 local time the city mean PM2.5 rose from 22.8 to 43.0 µg/m³.

Light wind (1 m/s) in the evening or at night, as the air cools, possibly traps particles near the ground (a temperature inversion). Cold weather (3°C) possibly means more heating, a common source of particles.

Weather now: rain, 3°C, wind 1 m/s, humidity 93%. No major change in the wind is expected in the coming hours.
