Paper Abstract

Our approach in addressing complex terrain scenarios is to utilize a high resolution wind (HRW) model that will provide a high resolution microscale analysis of the surface layer horizontal wind and temperature fields. The wind model uses Gauss' Principle of Least Constraints for a variational adjustment of an initial estimated wind field in a single surface layer to conform with terrain structure, mass conservation, and buoyancy forces. From meteorological measurements taken at a single location, HRW can calculate wind vectors over a 5 x 5 km area with grid points spaced 100 meters apart. These micrometeorological data as well as canopy information can then be used as inputs to the Rachele-Tunick model to calculate optical turbulence parameters at each grid point within the microscale area. The output will be 2D optical turbulence contours from which integrated line of sight turbulence calculations can be made.
