AB: Using atmospheric tracer transport models, inverse modelers can estimate the strengths and spatial distribution of carbon sources and sinks; however, fossil fuel CO2 emissions must be accurately estimated to isolate and quantify biospheric and oceanic fluxes. To help achieve unbiased estimates of carbon exchange, high-resolution fossil fuel emissions estimates (10 km spatial resolution at timescales of one hour) are being produced for the United States [Gurney et al., 2006]. To evaluate these emissions estimates and to investigate the impact of high- resolution emissions on the resulting atmospheric CO2 and CO concentration fields, we will use the coupled biosphere-atmosphere model SiB3-RAMS. Simulations across large urban airsheds will be evaluated against both CO2 and CO observations.
