in the ABL ( Kallistratova 1994 ; Emeis et al. 2007 ). Sodar-derived vertical velocities also provide a measure of convection intensity. For urban measurements, sodar has advantages over radar and lidar wind profilers. Unlike radar, it is not necessary to allocate an electromagnetic band for sodar, and relative to low-power lidar a sodar has a greater height range (higher-power lidar has greater range but requires further governmental approval). Moreover, the cost of a sodar unit is typically

the essence of whether remote sensing gives “bankable” data. What quality of wind measurements can be expected from remote sensing in a typical installation? This is relevant since intercomparisons are often under test conditions unlike those typically encountered at normal sites. Some previous intercomparison experiments have touched on the spatial and temporal separation issues treated in detail below. Mastrantonio and Fiocco (1982) describe transmission on three acoustic beams simultaneously

the case of scintillometer-derived fluxes, one compares a flux derived with MOST using experimental values of a stability parameter with a flux derived with MOST using a modeled stability parameter. It would be desirable to compare measured (e.g., from sonic anemometers, scintillometers, or acoustic remote sensing) with somehow derived from a model. For such a comparison, one has to be sure that is a reproducible parameter, at least in measurements—that is, that measured is representative
