Weekly Pollen Count Data for the Suburb of Casuarina, Darwin, NT 

The datafile contains the composition and abundance of airborne pollen in the suburb of Casuarina, Darwin, Northern Territory, Australia. The data was collected for the period between March 2004 to November 2005 as part of a large research program looking at atmospheric particles and human health (see Stevenson et al., 2007). 

We at TERN acknowledge the Traditional Owners and Custodians throughout Australia, New Zealand and all nations. We honour their profound connections to land, water, biodiversity and culture and pay our respects to their Elders past, present and emerging. This work was funded by ACEAS, a facility of Terrestrial Ecosystem Research Network (TERN), an Australian Government National Collaborative Research Infrastructure Strategy (NCRIS) project.

Airborne pollen counts were derived from deployment of a seven-day Hirst-type volumetric pollen and spore trap located on a rooftops at 14 m above the ground. The Hirst-type sampler uses a range of adhesive surface compounds including vaseline and 10% paraffin wax in toluene on MelinexTM tape (Burkard Manufacturing Co. Ltd., Rickmansworth, Hertfordshire, UK), silicon-based adhesive (Lanzoni s.r.l., Bologna, Italy). The seven-day tapes are then cut into 24-hr segments and mounted on glass slides with a stain such as fuchsine stained Gelvatol. Analysis of each 24-hr period is conducted by counting four transects at 400 magnification. The data is summed to provide an average weekly pollen count.
