Climate change and climate prediction are highly important issues of our time and part of the sustainable development goals.

Cosmic rays are known to impact cloud formation and cloud properties. Furthermore, connections between cosmic rays and other phenomena such as lightning and earthquakes are theorized. Currently the strength and importance of the correlation between these phenomena is mostly unknown. Thus the study of cosmic rays is essential for better understanding climate change and climate in general. Currently the needed large scale data is missing.

The CosmicPi project engages in this issue.

We are aiming to build the world’s largest open source distributed cosmic ray telescope.

Current CosmicPi prototype hardware and software are open and all available online. All hardware is designed to fit a low-cost budget of $350. The cosmic-ray-detecting part consists of a scintillator, made of a material that absorbs energy from cosmic rays passing through it and then emits some of that energy in the form of photons; an optic fiber to trap these photons and carry them to the edges of the scintillator material; and a silicon photomultiplier at each end of the fiber to convert this light into an electrical signal that can be analyzed by the computer.
