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 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).
This centre receives and archives precipitation chemistry data and complementary information from stations around the world. Data archived by this centre are accessible via connections with the WDCPC database. Freely available data from regional and national programmes with their own Web sites are accessible via links to these sites. The WDCPC is one of six World Data Centres in the World Meteorological Organization Global Atmosphere Watch (GAW). The focus on precipitation chemistry is described in the GAW Precipitation Chemistry Programme. Guidance on all aspects of collecting precipitation for chemical analysis is provided in the Manual for the GAW Precipitation Chemistry Programme (WMO-GAW Report No. 160).
The World Wide Molecular Matrix (WWMM) is an electronic repository for unpublished chemical data. WWMM is an open collection of information of small molecules. The "Matrix" in WWMM is influenced by William Gibson's vision of a cyberinfrastructure where all knowledge is accessible. The WWMM is an experiment to see how far this can be taken for chemical compounds. Although much of the information for a given compound has been Openly published, very little is available in Open electronic collections. The WWMM is aimed at catalysing this approach for chemistry and the current collection is made available under the Budapest Open Archive Initiative (
The NCDS is an EPSRC-funded service provided by the Royal Society of Chemistry to all students and other members of UK academic institutions.

Chempound is a new generation repository architecture based on RDF, semantic dictionaries and linked data. It has been developed to hold any type of chemical object expressible in CML and is exemplified by crystallographic experiments and computational chemistry calculations. In both examples, the repository can hold >50k entries which can be searched by SPARQL endpoints and pre-indexing of key fields. The Chempound architecture is general and adaptable to other fields of data-rich science.
The RRUFF Project is creating a complete set of high quality spectral data from well characterized minerals and is developing the technology to share this information with the world. The collected data provides a standard for mineralogists, geoscientists, gemologists and the general public for the identification of minerals both on earth and for planetary exploration.Electron microprobe analysis is used to determine the chemistry of each mineral.
The NADP monitors precipitation chemistry from numerous sites around the United States. The NADP consists of 5 networks: National Trends Network, Mercury Deposition Network, Atmospheric Integrated Research Monitoring Network, Atmospheric Mercury Network, and Ammonia Monitoring Network. Data is provided by each network.
The Alberta Food Composition Database (AFCDB) is the first comprehensive resource on food constituents, chemistry and biology dedicated to major Alberta-grown produce. It provides information on both macronutrients and micronutrients, including many of the constituents that give foods their flavor, color, taste, texture and aroma. Users can view the contents of the AFCDB from the “FoodView” (listing foods by their chemical composition) or the “ChemView” (listing chemicals by their food sources).
