This data set contains contains two ASCII files. One file, in comma-separated-values (.csv) format, provides above-ground net primary production (ANPP) and total NPP [expressed in grams of carbon per square meter per year (gC/m2/year)] and the C fraction used to convert dry biomass weight to carbon content for 127 unique study sites in northern Eurasia. The sites are classified by ecozone (i.e., ... tundra, forest-tundra, taiga, mixed forest, broadleaf forest, small-leaved secondary forests, forest bogs, meadows, steppe, semi-desert, and polar desert) and plant community (phytocoenosis). Each study location is georeferenced (latitude/longitude) with elevation and zonal/interzonal information. References to original author, year of publication, and table/record in Bazilevich (1993) are also included in the data file. The second ASCII file, in text (.txt) format, provides the bibliography of 274 original-source references (in Russian) to accompany the 127 data records on NPP from Bazilevich (1993). The data are a subset of data adapted from Bazilevich, N.I. 1993. Biological Productivity of Ecosystems of Northern Eurasia. Nauka Publishers, Moscow. 293 pp. (in Russian). The data set originated from field measurements of primary productivity collected between 1940 and 1988 for most of the terrestrial vegetation types in northern Eurasia.
