A field campaign was carried out from 26\udOctober to 7 November 1992, using the SOUSY-VHF radar and a mobile rawinsonde\udsystem installed and operated nearby to produce vertical wind profiles. The\udpurpose of this campaign was to compare the two types of wind measurements with\udone another and with results from forecast models. Numerical algorithms were\uddeveloped and applied to the radar data in order to eliminate random errors,\udcorrect for velocity aliasing, and calculate the effective zenith angle of the\udoff-vertical beams. Differences between wind profiler data and rawinsonde or\udmodel results depend not only upon the errors of the different systems, but also\udon temporal and spatial variations of the wind field. Therefore, methods for the\udcomparison of radar and rawinsonde data were developed which take into\udconsideration these variations. The practical potential of these methods is\uddemonstrated by comparisons of rawinsonde and radar wind profiles. The\udcomparison of radar data and model output shows excellent agreement in the\uddirection and in the speed of the wind at virtually all altitudes. An evaluation\udof the quality of wind profiler measurements is possible using the estimation of\udvariance and variability of wind components
