Twelfth Atmospheric Radiation Measurement (ARM) Science Team Meeting
Millimeter radars have been commonly used to examine the spatial/temporal evolution of clouds. To asses the impact of the cloud scale resolution on the solar radiative transfer, two sets of radiative experiments were performed by using high spatial and temporal resolution radar measurements from marine stratus (California, 1999) and fair-weather cumulus (Miami, 2000). In the first experiment, the original radar data collected by the University of Miami 94 GHz cloud radar (30-m vertical and 2-sec temporal resolution) was used. For the second experiment, the original radar data were rescaled to match the ARM MMCR resolution (90-m vertical and 10-sec temporal resolution). Results of the sensitivity analysis will be shown in order to determine whether the additional resolution has a considerable influence on the solar radiative properties.
