People love rainbows. The problem is that forecasters lack the... well, foresight, to give the people the lucious rainbow details they want. The idea to fill this gaping hole in supply came from Akira Kakkar at MHacks 6, and I'm lucky to call him, Jenny Zhang and Philip Tsang my co-developers on the project for those critical first 36 hours. I personally released an alpha a year later because this project's momentum isn't allowed to stop. For the sake of all that is round and colorful.
Detecting rainbows is feasible from just satellite and radar data, and boils down a geometry problem on these two datasets. From a quick detour into the mechanics of rainbows the problem statement will essentially just pop out.
