Abstract

Microphysical and radiative measurements in boundary-layer mixed-phase clouds were collected during a May-June 2008 tethered balloon campaign in Ny-Ålesund, Norway in the high Arctic. The instruments deployed on the tethered balloon platform included a radiometer, a cloud particle imager, and a meteorological package. The mean intensities estimated from the radiometer measurements on the balloon were used to quantify the vertical structure of the mixed phase cloud system, while the downward irradiances measured by an upward looking ground-based radiometer were used to constrain the total cloud optical depth. The time evolution of the liquid water and ice particle cloud optical depths was estimated by using a comprehensive radiative transfer model.
