Full Title earth - a visualization of global weather conditions.
List No 10126.000
Note Using data from the Global Forecast System, Earth visualizes worldwide weather patterns using animated wind streams, color coded according to velocity, that sweep across a three-dimensional globe. Truly interactive, the visualization allows the user to spin the globe and zoom in on a desired location. Tapping on that location will then bring up further information about exact coordinates, wind speed, and temperature, with all information updated every three hours. The world itself may be seen from different perspectives, as the visualization offers nine different projections, such as conic equidistant, stereographic, or Waterman Butterfly. When Earth was first introduced in December 2013, it only visualized wind patterns. Since then, however, Beccario has increased the number of overlays to include such factors as carbon monoxide concentration, dust and sulfate extinction, along with the measured temperature. Earth also shows the perceived temperature which Beccario calls the Misery Index, borrowing a term from economics.
