The authors wish to gratefully acknowledge the insight and support provided by Tom Horst and John Militzer. Thomas Foken provided the German references. The authors also acknowledge the assistance of K. K. Droegemeier, K. C. Crawford, W. H. Beasley, and R. Cox for their help in selecting, obtaining, and testing the FLUENT model. R.M. Young Co. constructed two of the part-time aspirated multiplate shields, and Sherman Fredrickson and the National Severe Storms Laboratory provided part of the instrumentation for the field site. Tim Hughes suggested incorporating a small fan inside a multiplate shield to reduce radiational heating errors. The scientists in the Mesonet calibration laboratory provided space and equipment necessary to perform calibrations. This work was supported in part by the Oklahoma Mesonet Project operated by the Oklahoma Climatological Survey and by the ARM Program of the U.S. Department of Energy through Battelle PNNL Contract 144880-A-Q1 to the Cooperative Institute for Mesoscale Meteorological Studies. Computer time was provided by the Pittsburgh Supercomputing Center (PSC) through an educational grant from Cray Research Incorporated; Ralph Roskies, Christine Ricci, and David Oneal were instrumental in being able to perform the necessary calculations at PSC.
