Abstract : Investigation of data obtained by aircraft during Project Rough Rider '71 reveals that aircraft navigation is unsatisfactory for mesoscale research on the convective cell scale. The established method for re-navigating the flights is modified to yield navigation errors of less than 0.1 nautical mile for most tracks when compared with entries in the navigator's log. It is shown that the corrections required are dependent on the height of the aircraft above the terrain, terrain slope and wind. Meteorological parameters obtained from aircraft measurements are compared with rawinsonde measurements. These comparisons show that if appropriate corrections are applied, the data are useful for extending rawinsonde networks and defining spatial gradients of parameters between stations. Recommendations for determination of correction factors and suggestions for further research are made. (Author)
