Eos I
Immersive term Atmospheric Science and Engineering weather balloon project 2019
As part of The Bay School's new immersive program, "atmospheric science and engineering" students take a three-week course in which they refine their understanding of Earth's atmosphere experimentally, designing and releasing balloon payloads to record data about different characteristics of the atmosphere. Eos I consisted of a fleet of three weather balloons that flew from the Bay Area to the Central Valley on the morning of June 7, 2019.
