Abstract
This is a report on atmospheric boundary layer measurements made aboard the USNS Kane in February and March of 1978. The data has been analyzed to obtain Monin-Obukhov similarity parameters and EM propagation properties using bulk, profile and turbulence data. The evaporation duct height, Z*, was found to vary from 1.0 meters to 25 meters with a typical value of 16 meters. A comparison with profile and turbulence methods showed that the bulk method was accurate to within a factor of two, although some of the disagreement has been attributed to profile measurement inaccuracies. A sensitivity analysis showed that the relative humidity and air-sea temperature difference are the most critical measurements for bulk calculations of Z*
