The LongEZ research aircraft (N3R) is ideally suited to the task of gathering near surface atmospheric and remotely-sensed ocean surface properties over large spatial scales at low altitudes (~10m) in short periods of time. It is an especially powerful tool for studying the spatial variablity of air-sea fluxes.
Data from a recent field experiment (CBLAST-Low) involving the LongEZ research aircraft will be presented. The plane is equipped with a three laser altimeter array and a nadir-pointing Ka-band scatterometer used to determine long and short wave characteristics, respectively, of the sea surface. The normalized radar cross section (NRCS) is computed from these instruments' data. Fluxes are determined using the eddy-correlation method. The effect of the sea surface roughness as characterized by the NRCS on the drag coefficient, Cd, is studied.
