The CAMEX-4 NOAA WP-3D Flight Level Data dataset used the NOAA WP-3D Orion aircraft, which collects numerous in-situ meteorological measurements along with navigation and aircraft state parameters during each flight. CAMEX-4 focused on the study of tropical cyclone (hurricane) development, tracking, intensification, and landfalling impacts using NASA-funded aircraft and surface remote sensing instrumentation. The WP-3D data are encoded on 8mm tapes in what is called the 'AOC Standard Tape Format'. Examples of meteorological data include total temperature, dew point, liquid water content and dynamic pressure (from several sensors). Aircraft parameters include angle of attack, airspeed, and slip angle. For further information and to obtain this data, please contact GHRC at support-ghrc@earthdata.nasa.gov
