Abstract: [1] Carbon dioxide is a stable constituent of the atmosphere that has no major terrestrial sinks other than atmospheric transport in the absence of photosynthetic activity by plants. In urban atmospheres, CO 2 mixing ratios are often elevated above ambient by large local sources from combustion. We measured CO 2 mixing ratios and the isotopic composition of CO 2 at four locations in the Salt Lake Valley, Utah, during a persistent cold pool event in the winter of 2004. The results showed a strong influence of …
