Abstract:

The present data report is based on direct turbulence and diffusion measurements performed by Risoe National Laboratory during the AMADEUS smoke tests of Project Wind, Phase IV, which took place as a cooperative research- oriented field effort between the U.S. Army Atmospheric Sciences Laboratory ASL and the U.S. Dept. of Agriculture Forest Service USDAFS in the Meadow Brook Valley near Red Bluff, California, between 23 September and 7 October 1987. In particular, Risoe National Laboratory performed 1 direct measurements of the surface layer scaling parameters such as heat flux, shear stress, turbulence, and stability measurements at two characteristic locations in the Meadow Brook Valley floor and 2 concurrently obtained documentation of the plume and puff spread based on aerial photography. The present report provides time series plots of the 10-min averaged covariance matrix of u, v, w, and T from the two sonics together with prints of photos taken of smokepuff plumes from an aircraft in a form suitable for subsequent model simulation of individual dispersion scenarios.
