| Outline of Final Research Achievements |
The lidar system was installed at Arctic station of National Institute of Polar Research at Ny Aalesund, Svalbard in March 2014 after preparation period. The lidar non-stop observes vertical distribution of aerosols and clouds. There has been no problem in the operation of the lidar system during the study period. The observations provide the data of aerosols and clouds for more than three years. Arctic Haze is known as high concentration Arctic aerosol particles found in winter and spring. However, our observations show that the highest concentration appears in spring to summer. The summer maximum is more clear at the altitudes higher than 5km where mainly the ice clouds are formed, and the maximum concentration appears in August at the altitude range between 8 and 10 km.
