Abstract

LAS (Large Aperture Scintillometer) observational data  at Guantao station  (from January to December) and A'rou station(from January to July and from October to November) in 2009 were used to analyze the applicability of MOST (Monin-Obukhov similarity theory) in LAS observations. The quantitative evaluation method was also discussed. The results show that: (1) The applicability of MOST is significantly influenced by the large-eddy movement, atmospheric turbulence development and temperature scale under unstable condition signally. (2) Two new evaluation methods, such as the factor analysis method and the temperature structure parameter method, are established. The rationality and reliability of these two methods are also proved by the validation results.
