Summary

Summaries and links to the data files used to create the charts in EarthViewer

The table below summarizes the data files used to create the charts in EarthViewer. Click on the links to open a tab-delimited text file. You can cut and paste the data into any software of your choice to graph and analyze the data for yourself.

Files are arranged by time period with "Modern" representing the years 1912–2012, "Paleo" representing 0–540 million years ago (Ma), and "Early Earth" representing 540–4567 Ma. The variables of oxygen, day length and luminosity, are each covered by a single file that spans all of Earth history.

You can also download all data files via this ZIP archive link: EV_data.zip
