CAMEX-4 ER-2 High Altitude Dropsonde

Capable of carrying up to 17 sondes in a special pod mounted ventrally on the centerline of the ER-2, the ER-2 High Altitude Dropsonde system to provided sounding data from an an altitude never before obtained in the tropical storm environment. Unlike sondes released from other airborne systems, sondes are loaded in the EHAD pod on the ground and are automatically selected and preflighted at altitude. Launch is commanded by the ER-2 pilot, and the sonde is spring ejected from the pod. Launched at approximately 20km (65,000ft), the sonde takes almost a full thirty minutes to reach the surface. The High Altitude Dropsonde system was first used during the CAMEX-4 experiment
