Soil methane flux data for Saddle, 1992.

Trace gas samples were collected from 3 alpine tundra vegetation community types (dry meadow, moist meadow, wet meadow) on Niwot Ridge saddle during the summer months of 1992 and 1993 (this data set contains data only from 1992). In addition, samples were collected from a set of control and nitrogen amended plots in both dry and wet meadow community types. Soil temperatures were measured in conjunction with the trace gas sampling. Methane fluxes were calculated from the gas concentration data.
