Designing an automatic pollen monitoring network for direct usage of observations to reconstruct the concentration fields.

Science of the Total Environment, 2023
We consider several approaches to a design of a regional-to-continent-scale automatic pollen monitoring network in Europe. Practical challenges related to the arrangement of such a network limit the range of possible solutions.

Methods and standards of pollen monitoring—significance of pollen measurements at different altitudes

Allergo Journal International, 2023
Background The measurement of pollen concentrations has been performed according to various protocols in recent decades. In all approaches the following questions were of importance: the positioning of the measuring device (whether at roof or nose level),

Towards automatic airborne pollen monitoring: From commercial devices to operational by mitigating class-imbalance in a deep learning approach.

Science of the Total Environment, 2021
Allergic diseases have been the epidemic of the century among chronic diseases. Particularly for pollen allergies, and in the context of climate change, as airborne pollen seasons have been shifting earlier and abundances have been becoming higher ...

Aerobiological Monitoring and Metabarcoding of Grass Pollen

Plants, 2023
Grass pollen is one of the leading causes of pollinosis, affecting 10–30% of the world’s population. The allergenicity of pollen from different Poaceae species is not the same and is estimated from moderate to high. Aerobiological monitoring is a standard method that allows one to track and predict the dynamics of allergen concentration in the air ...

Development and application of a method to classify airborne pollen taxa concentration using light scattering data

Scientific Reports, 2021
Although automated pollen monitoring networks using laser optics are well-established in Japan, it is thought that these methods cannot distinguish between pollen counts when evaluating various pollen taxa. However, a method for distinguishing the pollen
