DESCRIPTION:Radiocarbon is a valuable tracer used in various applications 
 that exploit the natural production and decay of radiocarbon\, or the "bom
 b" radiocarbon produced by nuclear weapons testing in the 1950s and 60s. I
 n atmospheric science and biogeochemistry\, carbon added by fossil fuel so
 urces can be quantified using radiocarbon because fossil-derived carbon ha
 s no radiocarbon\, in contrast to biologically-derived carbon. I will pres
 ent recent observation-based estimates of fossil fuel CO2 emissions in Cal
 ifornia using radiocarbon\, demonstrating that this technique can provide 
 independent validation of reported fossil fuel CO2 emissions. I will also 
 present on current work developing new methods for observing radiocarbon i
 n atmospheric CH4 to constrain fossil vs biological CH4 emissions.
