Identifying Urban Sources as Cause of Elevated Grass Pollen Concentrations using GIS and Remote Sensing [PDF]

open access: yes, 2013
We examine here the hypothesis that during flowering, the grass pollen concentrations at a specific site reflect the distribution of grass pollen sources within a few kilometres of this site.We perform this analysis on data from a measurement campaign in
