A field campaign was conducted to collect high quality vertical wind speed and temperature profiles with simultaneous turbulent momentum and sensible heat fluxes over the flat Gobi surface located at 39A degrees 09’N, 100A degrees 06’E at an elevation of 1,458 m during the Pilot Intensive Observation Period in 1990. Careful evaluation of the observations in near-neutral conditions supports a value of the von Karman constant close to 0.39, which is in good agreement with the results obtained from many other field experiments conducted in low elevation regions. In near-neutral stratification the turbulent Prandtl number is found to be 1 but with lower confidence due to scarcity and scatter of the data points. For an expanded stability range, exponents of -1/4 and -1/2 are respectively best fitted to the functional relations for the non-dimensional wind and temperature profile functions in unstable stratification but linear relations still hold for stable stratification in this high elevation region.
