Data resulting from the research for P concentrations in PM2.5 at Mt. Gongga, China

Atmospheric deposition is considered as an important source of phosphorus (P) to P- limited ecosystems. The PM2.5 samples were collected from a high alpine P-limited forest of Gongga Mountain (Mt. Gongga), eastern Tibetan Plateau from May 2015 to May 2016 to study the concentrations and identify the sources of total P (TP) and total dissolved P (TDP) in the atmosphere in a forest region at Mt. Gongga, China;
