The ARM Climate Research Facility uses a variety of airborne platforms to supplement its ground-based measurements. Manned and unmanned aircraft offer mobile platforms that provide data for the study of clouds and atmospheric radiation from above, below, and inside cloud layers. By flying at different altitudes, appropriately instrumented aircraft can measure the rate of energy absorption in the atmosphere, differences between up-welling and down-welling radiation, and cloud properties, such as phase, liquid water content, particle size and shape, etc. In addition, aircraft provide the means to physically sample the actual clouds.
