Urban area PBL study by means of Doppler sodar and cryogenic radiometer: Present status of research

Technical Report:

Abstract

With the aim of contributing to a deeper knowledge of the interrelation between radiative and dynamic energy exchanges in the planetary boundary layer (PBL) of an urban environment, two measurement campaigns were carried out in Rome, 12-18 Sept. 1990 and 16-22 Sept. 1991, using a tri-axial Doppler sodar operating in the monostatic mode and a cryogenic radiometer operating at about 850 micro m wavelength. The two instruments were operated simultaneously, the sodar for wind field characterization and the cryogenic radiometer for measurements of the associated radiation field and atmospheric temperature fluctuations. Depending upon the meteorological conditions, the two sets of data were found to exhibit fairly high values of correlation. Cross-correlograms are presented here between vertical velocity (averaged along 300 m in height) and radiometric data, for typical PBL conditions, together with scatterplots clearly showing the relation between the two data sets. Kinematic eddy sensible heat fluxes computed by using radiometric temperature rather than ground temperature values were found to be lower, as expected.
