艾力·买买提明，何清，霍文，刘新春 . 塔克拉玛干沙漠腹地LAS和EC观测感热通量对比分析[J]. 地球科学进展, 2010 , 25(11) : 1228 -1236 . DOI: 10.11867/j.issn.1001-8166.2010.11.1228
The sensible heat fluxes measured by Large Aperture Scintillometer（LAS） and Eddy Covariance system(EC) were compared. The data were collected at the Taklimakan desert atmospheric and environment OBSERVATION station located in the middle Taklimakan desert during the period of from June 20 to July 3,2009, which was supported by the Taklimakan deset Land-Atmospheric Interactive Experiment (TLAIE) project. The results show a similar variance trends and good agreement between sensible heat fluxes by LAS(HLAS) and EC(HEC), but HLAS tends to be slightly higher than HEC. The probability distribution function of HLASand HEC can be as high as 79% if the permitted difference is in the range of -50~50 W/m2. Therefore, we have reached the conclusion that the large aperture scintillometer is a reliable system for measuring sensible heat flux of large quicksand area as the Taklimakan desert.
