SYLVA's Demonstration Pilots include lidar observations in Granada (Spain), Munich (Germany), Potenza (Italy), and Kuopio (Finland), enabling vertical profiling of pollen in the atmosphere – a true innovation in real-time bioaerosol science.
Why lidars?
Non-spherical pollen grains generate strong laser depolarization, making them detectable through depolarization ratio measurements – especially in dust-free conditions. In SYLVA, we use this property to identify and quantify vertical pollen distributions in the atmosphere.
We have taken it further:
Lidars allow us to look up – and understand bioaerosols in ways not possible at ground level alone.
A new SwisensPoleno Jupiter measurement system has been successfully installed in Potenza, Italy, as part of SYLVA's pilot activities in southern Europe. This marks a major step forward for real-time bioaerosol monitoring.
What makes this setup special?
The SwisensPoleno Jupiter system will be cross-compared with data from a Hirst trap and a Raman lidar, located at one of Europe's most advanced ground-based remote sensing infrastructures – operated by our partner, Consiglio Nazionale delle Ricerche.
Breakthrough in bioaerosol tracking
We are deploying a pioneering pollen identification algorithm for multi-wavelength Raman polarisation lidars, enabling us to obtain the first-ever real-time vertical distributions of bioaerosols. Airborne pollen produces strong depolarisation signals, making it detectable even high in the atmosphere.
A deeper dive into vertical profiling of bioaerosols – coming up in our next news article. Stay tuned!

On 20 September 2024, the SYLVA project commenced a new phase of environmental DNA (eDNA) research, involving the collection of bioaerosol samples at Šiauliai Academy. Following the successful deployment of a high-volume air sampling device by BioSence in Novi Sad, Serbia, Vilnius University purchased a Precision Air device (from Univerzal komerc d.o.o.), which has now been installed at the Šiauliai Academy.
The purpose of this high-volume air sampler is to facilitate a deeper understanding of bioaerosols - airborne particles containing biological materials such as bacteria, pollen, and fungi. These particles have significant ecological and environmental implications, and their study can offer insights into the composition, sources, and dispersion of microorganisms in the atmosphere. From the sampled bioaerosols, researchers can extract environmental DNA to study biodiversity, track invasive species, and monitor environmental changes over time.
The installation of the Precision Air device at Šiauliai Academy strengthens SYLVA's research infrastructure. The air sampler allows for more efficient collection of bioaerosols, enabling the capture of a broader range of particles, including rare or less abundant organisms.
By complementing the existing research infrastructure, SYLVA enhances its capacity for advanced environmental research. The eDNA data generated from this sampling effort will contribute to improving bioaerosol dispersion models and facilitate a broader understanding of the ecological and atmospheric roles of bioaerosols. Through this research, the SYLVA project aims to provide a foundation for future studies in biodiversity and environmental monitoring.
SYLVA partners at Demonstration Pilot sites have been actively collecting samples of pollen, fungal spores, and DNA from a diverse range of region-specific and European taxa relevant to health, agriculture, and forestry. Northern taxa are contributed by the University of Turku, southern taxa by the BioSense Institute and the University of Cordoba, and high-altitude taxa by MeteoSwiss and the Technical University of Munich.
Our physical reference dataset (PRD) now contains nearly 400 samples from approximately 170 taxa across 10 countries. It is essential for creating high-quality digital reference datasets (DRD), which are used to calibrate and validate innovative bioaerosol monitoring technologies developed within SYLVA and beyond.
Stay tuned for more information on our DRDs, and don't miss SYLVA's training materials on collecting and storing pollen and spore samples.

And the best part? All data is freely available - with no limitations. Whether it's live data or archived records, the portal is designed to provide easy, unrestricted access to our rich data ecosystem. Explore the future of connected devices and data science with SYLVA bioaerosols!
In mid-August, our project partner Helmut Hund GmbH installed its BAA500 bioaerosol monitor in the heart of Pallas-Yllästunturi National Park, Finland, as part of the SYLVA Northern demonstration pilot.
Following the installation, fungal spores were successfully sampled shortly after the device became operational at the Pallas Atmosphere-Ecosystem Supersite.
Did you know that pollen generates strong depolarisation signals that can be used to detect the presence of bioaerosols in the air? Lidar systems are doing just that during the pollen season in Kuopio (FI), Hohenpeißenberg (DE), Granada (ES), and Potenza (IT).
The picture shows 4 days of observations at the Kuopio station: pollen concentration from the Burkard sampler at ground level (top), birch pollen concentration from the Finnish Meteorological Institute's SILAM pollen emission model (middle), and volume depolarization ratio (aerosol shape information) from the PollyXT lidar (bottom).
The southernmost SYLVA site in Cordoba has joined the pioneering alpine site at the Zugspitze mountain in delivering real-time pollen and fungal spore data to the international EBAS database. This advancement allows the public to access and monitor pollen and fungal spore levels in near-real time, providing valuable information for those affected by pollen allergies, engaged in agriculture, and contributing to ongoing environmental research.
To view or download the data, users can visit the EBAS database and select the framework "SYLVA_NRT." With two sites online, there is optimistic anticipation that northern locations in Finland will join the real-time data delivery soon.
EBAS is a database infrastructure operated by NILU - Norwegian Institute for Air Research. Since the 1970s, its main objective has been to handle, store, and disseminate atmospheric composition data generated by international and national frameworks, such as long-term monitoring programs and research projects.
Last week, Mikhail Sofiev from the Finnish Meteorological Institute participated in two meetings on behalf of SYLVA bioaerosols: first, the ACTRIS Scientific Conference 2024, and then the EO for Agriculture under Pressure 2024 Workshop, which brought together scientists and industry experts from all over the world.
The last session on Thursday consisted of over 20 lightning presentations of ongoing European projects, including SYLVA. The exchange continued throughout the next day, aiming to join forces and achievements of participating projects towards sustainable agriculture.
A high-volume air sampler has been installed at the BioSense Institute in Novi Sad, Serbia. Its purpose is to collect total suspended particulate matter from the ambient air without selecting for specific particle sizes. The vacuum motor pulls air onto the 1.6-micron glass fiber filter at a flow rate of 80-100 cubic meters per hour over a constant sampling period. The filter is then analysed to determine the identity of the particulates through environmental DNA (eDNA) sequencing.
SYLVA is developing the first end-to-end protocol for affordable sampling and identification of airborne bioaerosols using Nanopore's 3rd generation eDNA sequencing technology: an ultimate method to identify the entire spectrum of bioaerosols, including those undetectable by other instruments.
The sampler is custom made by BioSense in collaboration with the Finnish Meteorological Institute.
