The Airborne Vertical Atmospheric Profiling System (AVAPS) is a system mounted on aircraft that uses dropsondes and Global Positioning System (GPS) receivers to collect in situ atmospheric profiles. It provides measurements of temperature, pressure, and humidity every 0.5 seconds, and wind data every 0.25 seconds. AVAPS features a vertical resolution of about 10 meters and can launch dropsondes every 20 seconds. Developed by the National Center for Atmospheric Research (NCAR) for the NASA Global Hawk, it can also be used on other aircraft such as the DC-8 and P-3.
