Increased rupture of cypress pollen type due to atmospheric water in central and southeastern Spain
This study aims to investigate the meteorological variables determining Cupressaceae pollen grain disruption in the environment. A parallel sampling of pollen grains and disrupted Cupressaceae pollen grains was performed in six cities using two Spanish aerobiological networks. The pollen concentrati...

This study aims to investigate the meteorological variables determining Cupressaceae pollen grain disruption in the environment.

The concentrations were determined following the standardised method EN 16868.
