Atmospheric deposition and Chemistry of precipitation and snow from _ Bucegi - Piatra Craiului LTER_EU_RO_002

Air quality data represents concentrations of O3, NO2 and NH3 measured during the period 15.05-15.10 (monthly exposure) of years 2011 and 2012 in 11 plots in Bucegi-Piatra Craiului LTER site. Atmospheric depositions were measured during the whole period (2011-2012) in 6 plots. The reported parameters are: pH (determined by potentiometry), conductivity (conductimetry), nitrite in NH4 and inNH3 (water ion-chromatography) and alkalinity (titrimetric determination)
