For the purpose of understanding the characteristics of fog layer, atmospheric profile observations from ceilometer and unmanned aerial vehicle (UAV) carrying self-developed measurements were compared from October to December in 2014. The results showed UAV can observe up to 1200m height above ground level and it is more economical than traditional radiosonde instruments. The height of atmospheric boundary layer of Xitou valley was close to the around mountain ridges (~2000m a.s.l.) which was similar to the previous radiosonde observations (Wang, 2011). The ceilometer could provide water vapor profile under high temporal resolution; however it might underestimate the thickness of heavy fog due to the inability of clearly identifying the top height of the fog from the limit of laser power. A total solution of integrating ceilometer, UAV and remote sensing technology for monitoring/understanding the characteristics of Xitou microclimate change are on-going.
