Forecast.io has created a beautiful heatmap of planet Earth and MapBox has quickly put together an animated version on the map. The Forecast.io Temperature Map animates through global temperatures recorded on August 10, 2013.
The map uses the new Quicklsilver map from Forecast.io. Project Quicksilver is a high resolution real-time map of global temperature, that updates every hour. GeoTIFF images of the map can also be downloaded from Forecast.io.
