Insolation (Video)
a video showing total Insolation for the last 12 months. Insolation means "how much light hits the Earths surface".
Blue areas have least, white areas are in the middle and red areas have most.
Data from NASA Earth Observations.
Used QGIS to calculate the total insolation over the course of a year (with Raster Calculator) and render the map.
Country boundaries courtesy of Natural Earth.
Animation was done with Blender. Flight path seems a little crazy - it was designed to show all parts of the globe :-)
Interesting to see some odd anomalies - China, for example (caused by smog/pollution?) and the slightly less bright areas around the equator and tropics, which I assume are to do with cloud cover. Altitude will also have an impact (e.g. the Andes and Greenland being brighter)
