BOREAS TGB-01 CH4 CONCENTRATION AND FLUX DATA FROM NSA TOWER SITES
Get Data

Summary:

The BOREAS TGB-01 team made numerous measurements of trace gas concentrations and fluxes at various NSA sites. This data set contains half-hourly averages of ambient methane (CH4) measurements and calculated fluxes for the NSA-TF in 1996 and the NSA-BP and NSA-OJP tower sites in 1994. The purpose of this study was to determine the CH4 flux from the study area by measuring ambient CH4 concentrations. This flux can then be compared to the chamber flux measurements taken at the same sites.

A guide document which includes more information about this data set can be found at http://daac.ornl.gov/boreas/TGB/tgb1cfd/comp/TGB01_CH4_TOWER.txt .

ORNL DAAC maintains information on the entire BOREAS Project.
