The Airborne Vertical Atmospheric Profiling System (AVAPS) is an airborne system that utilizes dropsondes and Global Positioning System (GPS) receivers to collect in situ profiles of atmospheric state parameters. It provides profile measurements of temperature, pressure, and humidity at a sampling frequency of 0.5 s and measurements of atmospheric winds at a frequency of 0.25 s. AVAPS has a vertical resolution of about 10 m and can allow for dropsonde launches every 20 s. AVAPS was developed by the National Center for Atmospheric Research (NCAR) for the NASA Global Hawk, but it can be deployed on other aircraft such as the DC-8 and P-3.
