Multi-sensor observations of a dissipating tropical squall line were acquired during the 4th Convection and Moisture Experiment (CAMEX-4) and Keys Area Microphysics Project (KAMP). This paper will provide an overview of observations from the Mobile Integrated Profiling System (MIPS) located within a dual Doppler network having a 30 km baseline. In addition, the University of Connecticut X-band polarization (X-POL) radar, located about 6 km from the MIPS, acquired frequent RHI scans over the MIPS.
On 10 September 2001, kinematic and microphysical properties were measured by these systems within a weakening squall line that formed on the periphery of a developing tropical depression that eventually intensified to become Tropical Storm Gabrielle. Detailed observations of the squall line convective and stratiform structure were acquired over a 3 h period. Measurements from the MIPS are combined with the X-POL radar to infer the microphysical structure of convective and stratiform regions of the squall line. These measurements are placed in the context of mesoscale flows derived from dual Doppler radar analyses.
