Pollen levels, top three pollen lists, total counts and indices for the 2007 and 2009 pollen seasons from 12 NAB stations in the United States and one in Canada were compared to corresponding daily reports from the pollen count Web sites.
The researchers found that the predicted pollen information from the Web sites was different from the actual counts from the NAB stations.
