AB: Several atmospheric tracer measurements were made during NASA's CRYSTAL-FACE project in Key West, Florida during July of 2002. One of the primary goals of CRYSTAL-FACE was to measure the effect of convective systems, in particular cirrus anvil blow off, on high altitude tracer mixing ratios. Carbon monoxide (CO) was measured both in the boundary layer and in the upper troposphere. Generally, CO was found to be slightly enhanced, relative to the free troposphere, in the upper tropospheric convective cirrus clouds. These in situ results have been evaluated using DHARMA, a mesoscale model and will be discussed in this presentation.
