A meteorological measurement device","Vaisala Dropsonde RD41 is a meteorological measurement device for use in atmospheric profilings from aircraft flight level to surface. Descending through the atmosphere by a parachute, it measures the profiles of pressure (P), temperature (T), and relative humidity (U), and reads wind direction and speed data from the point of launch to the surface.","Features  • Designed for atmospheric profilings from aircraft flight level to surface  • Used for tropical cyclone reconnaissance and research, data acquisition over oceans as input for Numerical Weather Prediction (NWP) models, and in various field campaigns to acquire data for meteorological research and for validation of other airborne instrumentation  • Measures pressure, temperature, and humidity values, and reads wind direction and speed data from the point of launch to the surface  • Airborne Vertical Atmospheric Profiling System (AVAPSâ) onboard the aircraft receives, displays, stores, and distributes dropsonde data for further use","Key Benefits"," • Proven Measurement Performance   • Dropsonde RD41 is based on the same Vaisala-made sensors and unique measurement technology as the RS41radiosonde family.  • Designed for Aircraft Use   • Dropsonde RD41 is designed for aircraft use, and it is launched through the body of an aircraft. Specially designed launchers are used for both pressurized and unpressurized cabin aircrafts.  • Dropsonde Receiving System   • Onboard the aircraft, the AVAPS system receives, displays, stores, and distributes dropsonde data for further use.
