  skos:definition """National Trends Network (NTN): NTN is a 200-site network
 located in rural sites where rain and snow are collected
 weekly.  Precipitation samples are analyzed by the Central
 Analytical Laboratory (CAL) at the Illinois State Water Survey
 for constituents, including nitrate, sulfate, pH, and other
 major ions.  Field and lab quality assurance programs are
 included in the cost of the network to insure good quality data
 that are comparable among sites.  Data are presented in both
 tabular and graphical format on the web and in special
 publications within ninety days in draft form.  Sponsors
 include federal and state agencies, universities, public
 utilities and industry groups.
