Prediction for cloud spacing confirmed using stereo cameras

Abstract Using three years of the Clouds Optically Gridded by Stereo (COGS) product, mean cloud base, top, width, and spacing are described with respect to their seasonal and/or diurnal evolution at Atmospheric Radiation Measurement (ARM) Southern Great Plains (SGP) site. In addition confirming extending prior results, data show that effective diameter shallow cumuli approximately equal height above ground lifting condensation level (LCL). Furthermore, is found closely match a prediction Thuburn Efstathiou for horizontal scale largest unstable eddies in an unsheared convective boundary layer.
