Title:Monthly-mean bulk deposition chemistry, Tomakomai Experimental Forest, May 1990- April 1993
Identifier:JaLTER-toef-04.12.3
Abstract:
Monthly-mean chemistry of bulk deposition from May 1990 to April 1993 iin TOEF, Japan. Monthly mean values are calculated based on volume-weighted averege using the precipitation amount of each sample. Note that original data are also available in JaLTER metacat. The data are published in Shibata, H., and T. Sakuma (1994) Acid Deposition at Forest Regions in North-Western Part of Tomakomai, Jpn. J. Soil Sci. Plant Nutr., 65: 313-320.
