Description

This data set provides two data files in text format (.txt). One file contains a long time series of biomass measurements made between 1955 and 1989 on a semi-desert steppe at the Dzhanybek Research Station in Kazakhstan (49.33 N 46.78 E Elevation 20 m). The second file contains monthly and annual climate data for the study site for the period 1953-1989.

Peak live biomass measurements were made from 1955 to 1989 (excluding 1976) and additional measurements of above-ground live biomass and dead matter were made seasonally from 1985 to 1989. Averaged over the time series, above-ground live phytomass and standing dead were estimated to be 137 g/m2 and 32 g/m2 (dry matter weight), respectively, while below-ground phytomass dry weight was 1,750 g/m2. ANPP was estimated to be 201 g/m2/yr. BNPP and TNPP were not estimated.
Revision Notes: Only the documentation for this data set has been modified. The data files have been checked for accuracy and are identical to those originally published in 1997.
