A7 - Pollen stations - Measured values

MeteoSwiss operates the national pollen monitoring network. It consists of around 15 monitoring stations which cover Switzerland's most important climatic and vegetation regions. The measurements obtained provide invaluable information for those who suffer from allergies.

Additionally since 2023 the new automatic pollen network is operational: for the first time in the world, instead of daily averages being available after a week, airborne pollen concentrations (No/m³, number of grains per cubic metre of air) of Birch, Beech, Oak, Alder, Ash, Grasses and Hazel are available in real time at an hourly resolution.

7.1. Data granularity, update frequency, format and volume

There are files of data granularity h, d, m, y and update frequency hourly (now), daily (recent) or yearly (historical) for each station.

[!NOTE] The granularities h and d contain average pollen concentrations, while the granularities m and y contain pollen integrals.

Data format is CSV with an estimated volume of 0.6 MB per file.

See example data files for station PBS (set in lower case) for granularities h and d and update frequencies recent and historical: ogd-pollen_pbs_(data granularity)_(update frequency).csv.

7.2. Parameter metadata

See example parameter metadata files of data granularity: h and d.

7.3. Station metadata
