Climate and N flux data for Saddle, 1992 - 1995.
Atmospheric gaseous nitric acid (HNO3) plus particulate matter nitrate (NO3) and ammonium (NH4) concentrations were being measured at the Saddle site on an approximately biweekly basis during the winter and on a weekly to twice-weekly basis from April through September. These N species are the domin...
