Solution
Meteorology for air quality
How air pollution spreads is governed by the weather. We build weather stations and met masts measuring wind, temperature stratification, radiation and humidity at air quality stations and industrial sites – and deliver the data directly to Airviro or your own system.
))
What we measure
The basis for understanding and calculating air quality and the dispersion of emissions.
Wind direction and speed
Decide where emissions are carried and how quickly they are diluted.
Temperature at several heights
The temperature difference between levels on a mast shows whether the air is stable, for example during an inversion.
Turbulence
Fast ultrasonic sensors measuring how the air mixes.
Radiation
Solar radiation and net radiation, which affect the stratification of the air.
Precipitation and humidity
Rain washes out particles, and humidity affects how they behave.
Air pressure
Completes the input for dispersion calculations.
What your data can look like
The temperature difference between 50 and 2 metres shows when the air becomes stratified. During an inversion, emissions stay close to the ground.
Example with made-up values.

Frequently asked questions
Can you deliver data to Airviro?
Yes. We deliver data from the stations directly to Airviro, and to other systems when needed.
Can you take over service of existing stations?
Yes. We service weather stations at air quality stations and industrial sites, and can take over programs and data collection.
Do you also measure particles and gases?
We build the meteorology needed for air quality and dispersion, and connect it with your other measurements.
