AGU 2012 Session B067. The Role of Abiotic Processes in Terrestrial Greenhouse Gas Exchange

AGU 2012 Fall Meeting, San Francisco, December 3-7

B067. The Role of Abiotic Processes in Terrestrial Greenhouse Gas Exchange

Terrestrial systems are major sources and sinks of greenhouse gases (GHG). While biotic processes are commonly accepted as the major drivers of GHG production and consumption, the role of abiotic (i.e. physical, chemical or photochemical) processes is much less clear, but might be much more important than currently anticipated. This session aims at (i) synthesizing the state of current knowledge of and research into abiotic reactions involved in C and N trace gas formation and consumption in the soil and on soil and plant surfaces, such as reactions of nitrification intermediates with the soil matrix or photochemical production and destruction of GHG on surfaces; (ii) identifying knowledge gaps and research needs.
