Cloud Phase Determination Using Ground-Based AERI Observations at SHEBA

In the frigid environs of the Acrtic, ARM scientists at the North Slope of Alaska/Adjacent Arctic Ocean (NSA/AAO) site are studying cloud and radiative processes at high latitudes. Data from these research efforts are being used to refine climate models and parameterizations as they relate to the Arctic environment. Now, a new algorithm that uses ground-based spectrally resolved infrared observations with thresholds determined from radiative transfer simulations will allow scientists to create the first climatology of cloud phase at the ARM site in Barrow, Alaska.
