Cirrus Cloud Optical Properties Derived from AERI Measurements

DeSlover, D.H.(a) and Turner, D.D.(b), University of Wisconsin - Madison; Cooperative Institute for Meteorological Satellite Studies (a), Pacific Northwest National Laboratory (b)
Fourteenth Atmospheric Radiation Measurement (ARM) Science Team Meeting

We demonstrate a continuing effort to develop and enhance a robust algorithm to discern ice particle effective size and infrared spectral absorption optical depth from AERI radiance measurements. Spectral absorption optical depths were retrieved using the high spectral resolution infrared measurements combined with lidar measured cloud boundaries. The spectral variation in each optical depth measurement were used to infer cloud particle effective radius from a database of hexagonal column extinction calculations. Cases selected by the Cloud Properties - High Cloud Working Group will be emphasized and results used for intercomparison (Comstock et al.) with techniques utilized by other investigators.
