NSSL is working on an experimental instrument train attached to a weather balloon that includes a radiosonde (temperature, relative humidity, wind, altitude), an electric field meter, and a PArticle Size, Image, and Velocity probe (PASIV). The PASIV has an HD camera and a disdrometer. New though, is a GoPro camera attached to the train above the radiosonde looking down as the balloon rises. Excerpts from the video coming soon!
