Project Eos

Eos 1 Patch

Immersive term Atmospheric Science and Engineering course

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.

You can track their locations on aprs.fi.

More details to come!
