It can be sourced back to Cameron Beccario's project getting some exposure in late 2013 after launch as open source. https://github.com/cambecc/earth

For the record: windy, launched as windity in late 2014, this was 1 1/2 years before ventusky:
"ventusky is owned by InMeteo, built to compete with windyty, which was originally a copy of my site's open source repo"
"if you're curious: http://hint.fm/wind launched Mar? 2012, e.n.n Dec 2013, windyty Nov 2014, and ventusky Jul 2016"
