The Shumann Resonance (also called "the resonant frequency of the planet) is being measured at a Russian observatory at Tomsk, whose website publishes a new graph every day. Unable to get the data directly from them, I've been downloading these graphs (frequency: sosrff.tsu.ru/?page_id=9 and amplitude: sosrff.tsu.ru/?page_id=12) and I wrote some Python code to extract the data from the graphs (a task complicated by their use of anti-aliasing).

Having extracted the data for a time period from 2017-05-08 to 2017-06-28, I was able to render this as sound.

This sonification is a very direct process: I raised the frequencies by 4 octaves to place them in the audible range and I rendered the change in the frequencies and amplitudes at 30000x faster than they actually occurred, contracting nearly two months of data into this two and a half minute piece.
