As part of a joint NSF and NOAA HRD project, the Hurricane Air-Sea Interaction (HAIRSIN) Experiment was conducted prior, during and subsequent to the passages of Hurricanes Isidore and Lili (2002). These data were acquired from 24 research flights using GPS sondes for the atmospheric structure, the Stepped Frequency Microwave Radiometer for surface winds, Scanning Radar Altimeter for surface waves, and AXCPs, AXCTDs and AXBTs to observe the evolving upper ocean fields. The particular focus here is to examine boundary layer and near-surface processes using the GPS sondes to determine the evolution of their structure relative to the large-scale atmospheric environment observed from the Gulfstream-IV jet flights. Variations in the atmospheric fields will be correlated to upper ocean features. Of particular interest is to document intensity changes relative to upper-ocean features such as the Gulf of Mexico Loop Current and the surrounding common water. .
