Col d'Olen, snow chemistry (N-NO3) 2009-2019

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 from 2009 to 2019 before snowpack isothermal condition (to avoid losses via ionic pulse). Nitrate stored in snowpack is rilevant on yearly ion balance.
