The report is a continuation of the work included in Technical Report ECOM-0280-6 regarding the investigation of the suitability of an alternate expression for the exchange coefficients for momentum which are an integral part of the set of meteorological equations presently being used to simulate the atmospheric boundary layer. Solutions for Cases I-B, II, III, and IV-A of the Dallas Tower Network data incorporating the alternate exchange coefficient are included in the report. These solutions indicate that the alternate expression for the exchange coefficient for momemtum produces more realistic results which are consistent with the expected diurnal variation of the exchange coefficients and which yield predicted winds at 8-m height which are closer to the observed values for long time intervals than those winds predicted by the original exchange coefficient relationship.
