Dropsonde RD41

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.

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
