The Airborne Radio Occultation (ARO) is an airborne passive sensor that detects refractive delays in radio signals from the Global Navigation Satellite System (GNSS). ARO uses these measurements to determine the vertical profiles of temperature and water vapor in the atmosphere. It has a horizontal spatial resolution of 150-250 km and a vertical resolution of 200-400 m. ARO has a sampling rate of 1 Hz and typically collects about 45 profiles per flight.
