Abstract:

The Phoenix 2 data analysis project was aimed at developing techniques for applying Doppler radar to observations of the turbulent boundary layer and at defining the important statistical properties and the large eddy structure more completely than is generally possible with direct sensors. An array of direct sensors was applied for comparison and to observe some of the finer scales of turbulence not accessible to the radar. A large eddy simulation experiment was also carried out for the purposes of observational comparison and improved interpretation. The original emphasis was on technique development in an environment thought to be moderately well understood. In outcome the technological developments are mixed in quality and some remain incomplete, while the scientific results are much more interesting than originally expected. Important improvements were made in single and dual Doppler processing, and satisfactory comparisons made between them. The errors in vertical velocity from the dual Doppler remain unpleasantly large in the upper levels and the effective resolution for some fields disappointingly coarse.
