Comparison of Boundary-Layer Wind and Temperature Measurements with Model Estimations.

Abstract

Five simple models that estimate vertical profiles of wind speed or temperature in the boundary layer were evaluated by comparing the predictions with measured data. The models evaluated consist of three Monin-Obukhov similarity algorithms for predicting wind speed and temperature, a p-profile algorithm for estimating wind speed, and an inversion algorithm for estimating temperature. The data for the study was collected by towers, sodars, and radiosondes at four field experiments in 1990 and 1991. Using one or two levels of the tower measurements, wind speed, and temperatures were predicted at several measurement heights. The predicted and measured data were statistically compared. The results are presented in this report showing the comparability of the model predictions as a function of height above the surface and time of day.
