Description
Summary:The goal of this study was to determine under what meteorological conditions, if any, measurements of aerosol properties made at the Earth's surface are representative of aerosol properties measured within the column of air above the surface. Specifically, this study uses instrumentation from the Atmospheric Radiation Measurement (ARM) Program's Southern Great Plains (SGP) site to determine how the observed mixing height (MH) and the degree of mixing affects the vertical variation of aerosol extensive and intensive properties. The MH was estimated by applying the Heffter [1980] technique with a critical lapse rate of 0.001 K m@@u-1@ to the available radiosonde data. This estimate was then used to determine whether each vertical aerosol profile flight leg from 59 flights was within or above the atmospheric boundary layer (ABL). Although the aerosol extensive properties, such as light absorption by particles
