An excel file containing all of North Carolina Department of Environmental Quality historical pollen counts from 1999 to the 2016. Gaps in the dates could be due to sampler issues and/or end of season. Typically, pollen season is from February through November. The counts listed are total pollen grains found for a particular type (weed, tree, or grass). To get concentration (grains/m3) divide the pollen grains by 3.12.
