description |
International audience Cloud observations in the Arctic are still rare, which requires innovative observation techniques to assess ice crystal properties. We present an original approach us- ing the Raman lidar measurements applied to a case study in northern Scandinavia. The vertical profiles of the optical properties, the effective radius of ice crystals and ice water content (IWC) in Arctic semi-transparent clouds were as- sessed using quantitative ground-based lidar measurements at 355 nm performed from 13 to 26 May 2016 in Hammer- fest (north of Norway, 70◦39′48′′ N, 23◦41′00′′ E). The field campaign was part of the Pollution in the ARCtic System (PARCS) project of the French Arctic Initiative. The pres- ence of low-level semi-transparent clouds was noted on 16 and 17 May. The cloud base was located just above the at- mospheric boundary layer where the 0 ◦ C isotherm reached around 800 m above the mean sea level (a.m.s.l.). To ensure the best penetration of the laser beam into the cloud, we se- lected case studies with cloud optical thickness (COT) lower than 2 and out of supercooled liquid pockets. Lidar-derived multiple scattering coefficients were found to be close to 1 and ice crystal depolarization around 10 %, suggesting that ice crystals were small and had a rather spherical shape. Us- ing Mie computations, we determine effective radii between ∼ 7 and 25 μm in the clouds for ice water contents between 1 and 8 mg m−3, respectively. The uncertainties regarding the effective radii and ice water content are on average 2 μm and 0.65 mg m−3, respectively. |
