            <gco:CharacterString>Air Monitoring Networks and Studies produce data that represent a wide variety of observations and measurements.  Multiple data types (also called collections) can be produced by a single network and data collections can have contributions from multiple networks.  The data are organised as follows:

               1. Atmospheric Gases, 
               2. Atmospheric Particles, 
               3. Atmospheric Precipitation Chemistry, 
               4. Combined Atmospheric Gases and Particles 
               5. Special Studies of Atmospheric Gases, Particles and Precipitation Chemistry 

               Networks and Studies contributing to the Canadian National Atmospheric Chemistry Database and Analysis system (NAtChem) are from Canadian federal and provincial networks (past and present) and also include U.S. historical networks (these data are not available elsewhere).   Information about these contributing networks, for each of these collection and product groups, can be found in each network's description documentation.</gco:CharacterString>

Un seul réseau peut produire de nombreux types de données (collections) et plusieurs réseaux peuvent contribuer à des collections de données. Les données sont structurées comme suit:

                     Les réseaux et les études qui contribuent à la base de données nationales sur la chimie atmosphérique et le système d’analyse (NAtChem) regroupent des réseaux provinciaux et fédéraux canadiens (passés et actuels) ainsi que des réseaux américains passés (les données recueillies sont uniquement versées dans la base de données NAtChem). On trouve des renseignements sur les réseaux contributeurs, y compris sur chaque collection et groupe de produits, dans la documentation descriptive de chacun des réseaux.</gmd:LocalisedCharacterString>
