Col d'Olen, snow chemistry (N-NO3)

Dataset provides information about soil temperature, soil C and N dynamics at different sites in the alpine tundra, along an elevational gradient from 2500 to 2900 m asl during the period 2005-2018. Moreover, one snow profile was opened every year before snowpack isothermal condition (to avoid losses via ionic pulse). Nitrate stored in snowpack is rilevant on yearly ion balance.
