This study analyzes the pollenrepresentation of Cupressaceae in theatmosphere of Santiago de Compostela (NWIberian Peninsula) during the years 1993–1998.The samples were collected with a Hirstvolumetric spore trap, situated at a height of27 m above ground level on a building situatedin the south of the city. Cupressaceae pollenis present in the atmosphere practically allyear round, although it is predominant in thewinter period along with Alnus andPinus, standing out due to its markedallergenic nature. During the period understudy 5,128 grains were recorded, whichrepresented 5% of the total pollen identified.The principal pollination period for thispollen type in each sampling year and itsintra-diurnal variation were calculated. Thecorrelation between the pollen content of eachyear and the main meteorological parameters islikewise presented.
