Size distributions of aerosol particles and cloud droplets, concentrations of cloud condensation nuclei, radon, and ion were measured continuously at the summit of Mt. Fuji from 20 July to 20 August 2015. Size distributions of aerosol particles larger than 0.3?m were measured with an optical particle counter (OPC, KC01E) at the second floor of first building (Fig. 1).  Size distributions of aerosol particles, concentrations of radon and ion, and sky radiometer were measured from last fall continuously at Tarobo, the foot of Mt. Fuji. Lidar and Doppler Sodar observations were also performed at Tarobo from 3 to 22 August by Dr. Yabuki, Kyoto University. And Kytoon and Sonde observations were performed at Tarobo from 3 to 5 August.
