Large Aperture Scintillometers(LAS)Observation in Semi-arid Regions of Northwestern China
|
Abstract:
In this paper,sensible heat flux in semi-arid region of northwestern China were calculated and analyzed by use of the observation data of Large Aperture Scintillometers(LAS) recorded per 30 minutes,the temperature,pressure data,and the observation data by Eddy Covariance System at Lanzhou University Semi-arid Climate and Environment Observatory during summer and winter of 2007.The values of the sensible heat flux in summer were bigger than that in winter,and there was a lag of peak value on diurnal variatio...
