The Canadian National Atmospheric Chemistry (NAtChem) Database And Analysis SystemThe National Atmospheric Chemistry Database (NAtChem) is a data archival and analysis facility operated by the Meteorological Service of Canada. The purpose of the NAtChem database is to enhance atmospheric research through the archival and analysis of North American air and precipitation chemistry data. Such research includes investigations into the chemical nature of the atmosphere, atmospheric processes, spatial and temporal patterns, source-receptor relationships and long range transport of air pollutants. The NAtChem Database contains air and precipitation chemistry data from many major regional-scale networks in North America. To contribute to NAtChem, networks must operate for a period of at least two years, must have wide area coverage, and must have regionally-representative sites (rural and background). The NAtChem Database consists of 4 smaller databases:
