National Atmospheric Deposition Program Pollen Study Data for 2021 Pollen Season Pollen was measured in ambient air by several methods and in wet atmospheric deposition samples at three monitoring sites in the National Atmospheric Deposition Program (NADP) National Trends Network. A method for counting pollen on filters was developed and provided pollen counts for NADP atmospheric wet-deposition samples and high-volume ambient air samplers (HVAS) for comparison with co-located traditional microscopy and PollenSense sensor counting methods during the 2021 pollen season. Air and precipitation samples were collected by the NADP and analyzed by the Wisconsin State Laboratory of Hygiene, in Madison, Wisconsin and Aerobiology Research Laboratories (Canada). Daily data were obtained from online summaries... Categories: Data; Tags: Botany, Climatology, Draper, Utah, Duke Forest, North Carolina, Ecology, All tags...

The PCQA is primarily focused on data quality for the NADP National Trends Network (NTN) and Mercury Deposition Network (MDN). The PCQA implements programs to evaluate the variability and bias of NADP data. The programs are described in several USGS reports: 1. See, R.B., Willoughby, T.C., and Brooks, M.H., 1990.

As of fall 2023, precipitation was being collected at approximately 260 NTN sites in the United States, including Puerto Rico and the U.S. Virgin Islands, and additionally Bermuda and Canada. Beginning in 1996, the NADP/Mercury Deposition Network (MDN) has monitored mercury (Hg) in precipitation, and includes approximately 80 sites in the United States including Puerto Rico, plus Canada and Taiwan. The U.S. Geological Survey started the Precipitation...

Beginning in December 2016, the PCQA installed and began operating NTN monitoring sites in the Denver-Boulder metropolitan area to study urban reactive nitrogen wet deposition. Precipitation depth data are collected at 15-minute intervals using electronically recording precipitation gages, and weekly composite samples are obtained using automated mechanical collectors. The precipitation depth data are summarized into daily, monthly, seasonal, and annual records. The samples are analyzed by the NADP Central Analytical Laboratory...
