Annual aggregates of dry deposition flux, calculated from weekly aggregates of dry deposition velocities (MODEL_OUTPUT_WEEK) and measured concentrations (DRYCHEM_WEEK). Missing hourly deposition velocities were replaced with hourly averages, where available.
Network Overview:
The Clean Air Status and Trends Network (CASTNET) is a national air quality monitoring network designed to provide data to assess trends in air quality, atmospheric deposition, and ecological effects due to changes in air pollutant emissions. CASTNET began collecting measurements in 1991 with the incorporation of 50 sites from the National Dry Deposition Network, which had been in operation since 1987. The National Park Service (NPS) operates more than 20 CASTNET sites within national parks and Class 1 areas. The Bureau of Land Management, Wyoming State Office joined CASTNET in 2012 when they converted five Wyoming Air Resource Monitoring System (WARMS) sites to CASTNET protocol sites. CASTNET provides long-term monitoring of air quality in rural areas to determine trends in regional atmospheric nitrogen, sulfur, and ozone concentrations and deposition fluxes of sulfur and nitrogen pollutants in order to evaluate the effectiveness of national and regional air pollution control programs. CASTNET operates more than 85 regional sites throughout the contiguous United States, Alaska, and Canada. Sites are located in areas where urban influences are minimal.
