Pollen monitoring in real time

Ecosystem Pollen Monitoring

Pollen allergy is a largely underestimated disease. At the same time, pollen plays a crucial role in the Earth system, especially in the interactions between atmosphere, biosphere and climate. In the public health focus, the interaction of pollen exposure, air pollution and climate change is leading to an increasing number of pollen allergy sufferers. 

Better pollen information for allergy prevention, medicine and science is needed to better understand the interactions and counteract the increasing number of pollen allergy sufferers.

Challenges of real-time pollen monitoring

The current information available in Europe on the main pollen species in the air is largely determined by manual measurement methods. For operational monitoring, manual measurement methods provide low temporal resolution and require elaborate laboratory processes to measure and identify pollen concentrations. This leads to incomplete and time-delayed pollen information.

Real-time measurement of pollen

Automated real-time measuring instruments provide data every hour or even every minute without time-consuming ancillary processes. However, they also bring new requirements in operational use.


The solution is therefore not a single measuring system, but a combination of components for reliable real-time pollen monitoring.


Characteristics of real-time pollen monitoring

  • reliable and tested measuring principle
  • continuous quality assurance
  • use of artificial intelligence
  • integrated algorithms for pollen identification
  • seamless extension of algorithms to local flora
  • fully automatic operation and low maintenance
  • Integrated data management and BigData processing

New standards in pollen monitoring

MeteoSwiss pioneers the automation of the pollen measurement network. Swisens convinces MeteoSwiss and supplies the systems for the nationwide Swiss Automated Pollen Network.

Swiss Automated Pollen Network

In close scientific cooperation with the renowned Federal Office of Meteorology and Climatology MeteoSwiss, Swisens has developed a special solution for real-time pollen measurement. Swisens supplies the  the nationwide pollen measurement network “Swiss Automated Pollen Network” and supports MeteoSwiss in this unique pioneering achievement. The entire network with 18 monitoring stations will be ready for use in 2022 and will set new standards for automated pollen measurements in Europe and around the world.

SwisensEcosystem Pollen Monitoring

Both the scientific community and pollen monitoring station operators are in need of better and more reliable real-time pollen monitoring data. Swisens offers a comprehensive monitoring system consisting of hardware, software and service components. Through the intelligent combination of components, the Swisens ecosystem provides comprehensive support in dealing with the latest technologies and thus paves the way for the new era of real-time pollen monitoring.


The automated pollen measurements of Swisens, identifies pollen within seconds and allows the calculation of the actual local pollen concentration with a time resolution in the range of minutes.

With reliable results from SwisensPoleno Mars, clear data management and transparent data generation, this data can be used as input for pollen forecasts and numerical models.

“Swisens has shown to be a service-oriented partner in any case, addressing requests diligently. Our suggestions have always been heard and have been systematically translated in technical improvements. In short, Swisens AG has shown to be strongly oriented towards client and market needs. Finally, the tests we performed with Swisens AG resulted in a fruitful scientific exchange. In all, it is for us a great pleasure to recommend Swisens AG for operational or research projects in the field of automatic pollen measurements.”

“I speak on behalf of my colleagues who are Urban Observatory Principal Investigators and Research Collaborators from the University of Manchester that we have rarely seen, or been provided with such exemplary support as that provided by Swisens. Swisens customer support has been remarkable given the current situation, from remote training and commissioning to rapid support for hardware and software tools specific to our needs to extremely well organised seminars that actually focus on customer feedback and needs. In particular we have been impressed with the Swisens open source data approach and their attention to different users specific needs. Swisens technical innovations has already generated enormous interest in a bioaerosol-aerobiology community that until recently has been limited with respect to real-world and near real-time detection and importantly quantification of airborne bioaerosol concentrations. Their approach has developed significant rapport with multi-disciplinary researchers and Swisens should be lauded for this.”

Finnish Meteorological Institute

“The Finnish Meteorological Institute is very satisfied with the cooperation of Swisens AG. The agreed research and development programme is progressing well and mutual openness and collaborative atmosphere strongly supports it. Swisens participated in a workshop and supported the scientists in recording the test data based on the cooperation agreement. A particular outcome of the workshop was a new procedure for the calibration of real-time monitoring systems based on the SwisensAtomizer. It has been proven to deliver cleaner results than the approaches tried so far in different countries. FMI is very satisfied with cooperation of Swisens AG. Our suggestions regarding software tools were quickly accepted and implemented by Swisens engineers. We are indeed happy to work with Swisens and start opening real-time data to professionals in Finland.”

Team Leader
Department for Work Safety / Health Protection

“Being able to aerosolize different powder samples in the lab to perform experiments related to occupational health has been one of our challenges. With the SwisensAtomizer at hand, we now have a small device which helps us to produce a stable dust atmosphere to load filters in a consistent manner, serving as calibration filters for later analysis. Swisens AG has always shown great support concerning our demands on the SwisensAtomizer. We are delighted to collaborate with Swisens AG.”
