  <dc:description>The chemical content of precipitation was monitored during the period  1980-94 at three sites at altitudes above 2,400 meters near the Piceance  Basin in northwestern Colorado.  Daily precipitation volumes, specific  conductance, pH (in this report pH is expressed as hydrogen-ion concentration), concentrations of major cations and anions, calculated  charge balance between cations and anions, and summary statistics of  chemical concentrations are tabulated.  Sampling sites are plotted on a  map of the area.  Seasonal variabilities of major cation and anion  concentrations are presented graphically.</dc:description>
