Abstract

Current estimates of atmospheric growth of key trace gas species are based on scanty measurements of the sources and sinks of these compounds. The terrestrial processes controlling the fluxes of these trace gas have been studied over the past decades, but a coordinated effort to synthesize these studies and to analyze the environmental controlling factors has not been conducted. A critical synthesis of information on the biotic and abiotic controls of trace gas fluxes is needed in order to advance our ability to determine regional estimates of various trace gas compounds. The U.S. TRAce Gas NETwork (TRAGNET) is developing an accessible data base of multi-year trace gas flux data (and ancillary data) from a range of ecosystems across North America, contributed by a number of independent research groups. TRAGNET also includes several trace gas flux models, which have not yet been tested against most of the TRAGNET flux data.
