Sodar 101 & Dr. Staebler's Atmosphere Studies (Ralf Staebler)

Video Shot in: 2009

Dr. Ralf M. Staebler explains the SODAR, a device that measures wind speeds and directions in the atmosphere. By emitting sound pulses and analyzing the frequency shifts (the Doppler effect) of echoes, it calculates the wind conditions up to a kilometer above the ground. The SODAR also provides insights into the stability of the atmosphere and helps determine the depth of ozone depletion. Dr. Staebler highlights the portability and advancements of modern SODAR technology. He shares a story about a polar bear visit to their research site, which resulted in minor damage to the instruments. Overall, the conversation showcases the importance of SODAR in atmospheric research.
