This paper reports on an application of the Turbulent Transfer Model (TTM) for the atmospheric reduction of long-range geodolite EDM measurements. To apply the TTM, additional meteorological parameters must be determined. For this application, the sensible heat flux, which is central to the modeling of the vertical temperature gradient, has been empirically modeled. The atmospheric reduction obtained with the TTM is compared to both the distance corrected for refraction by the standard reduction technique, and the “true” distance which has been determined using temperatures measured along the wave path by an aircraft. The results indicate that the TTM can yield a significant improvement in accuracy over the standard reduction for long-range electrooptical EDM. To attain this improvement only a few additional, and mainly qualitative field observations need to be recorded.
