Engineering Lesson 16: Gravity Wave Analysis
Overview of the content
To better understand the Engineering Gravity Wave Analysis below are some resources to get you started in Fall 2023. We will be providing code for analysis if your team wants to analyze your own data.
An extensive learning unit will be provided after the holiday break that walks those interested through the details of this analysis.
Additional information and resources will be provided as they become available, so check back soon.
Gravity Wave Methods Overview. Free copies of this book may be available online.

Surfs up! It’s time to catch an atmospheric wave as we launch Gravity Wave Zoo!
In Gravity Wave Zoo, we ask you to identify gravity waves, instabilities, and aurora in short video clips. The pictures were taken using a camera that views in the infrared, equipped with a fisheye lens, so they show the detail in a large part of the sky. Classifying these events will help us understand how energy is transported through the atmosphere. Anyone can do Gravity Wave Zoo, and there is not always a "right" answer. If you're not sure, just take your best guess!
