Surface roughness during depositional growth and sublimation of ice crystals
(2018-09-27)
Ice surface properties can modify the scattering properties of atmospheric ice crystals and therefore affect the radiative properties of mixed-phase and cirrus clouds. The Ice Roughness Investigation System (IRIS) is a new ...
Characterizing ice particles using two-dimensional reflections of a lidar beam
(2017-07-01)
We report a phenomenon manifesting itself as brief flashes of light on the snow surface near a lidar beam. The flashes are imaged and interpreted as specular reflection patterns from individual ice particles. Such patterns ...
