The Canadian National Atmospheric Chemistry Database
Also known as La base de données nationales sur la chimie atmosphérique · NAtChem · The Canadian National Atmospheric Chemistry Database and Analysis System
The National Atmospheric Chemistry Database (NAtChem) is a data archival and analysis facility operated by the Science and Technology Branch of Environment and Climate Change 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 NA…
