Ammonium in LTER-Europe research site: Lake Paione Inferiore (1984-2013)

Dataset provides information about nitrogen as ammonium (N-NH4 in ��g L-1) in Lake Paione Inferiore (LPI) at different layer depths along the water column collected at least twice per year (late summer/autumn) within the period 1984-2013.
Lake Paione Inferiore is a high altitude Alpine lake, located at 2002 m a.s.l. in the Bognanco Valley, Province of Verbania, Piedmont Region, Italy.
