Researchers from Penn State University used Sparv’s novel instrument “Swarmsonde” for a research project earlier this year. The purpose was to capture thermodynamic data within and around a tornado. The data obtained will help explain how tornadoes are formed. This new instrument can measure up to 32 sondes at the same time and stay in the air for more than an hour. Click on Swarmsonde for specifications about the sounding tool.
