Clear air radar angels were tracked with an FPS-16 radar at Wallops Island, Virginia. Observations were made at different times of the year under a variety of weather conditions. On cloudy days, echoes having characteristics similar to clear air angels were tracked. The radar had a beam width of 1.2 degrees, a wavelength of 5.5 centimeters, and was operated at a pulse length of .25 microsecond with a peak power of 1.2 megawatts. Data consist of flight trajectories of the echoes and a record of power returned. Radiosonde profiles of the atmosphere were obtained from an on-site weather station. It may be that this kind of data can not only clarify the angel problem but also provide convenient means for studying local atmospheric motions, such as the sea breeze. Evidence is given that indicates the meteorological nature of angels. A tentative model is suggested would account for most of the observed characteristics.
