Earth ID: 3935

Modelling Weather: Wind, Clouds, and T2M.

Visualizations by Alex Kekesi Released on March 26, 2012

This visualization shows a Goddard Earth Observing System Model, Version 5 (GEOS-5) run for most of the month of June, 2005. The simulation was seeded at the beginning of the run and then ran on its own to create a 2 year simulation. Only 25 days of the full run are depicted here.

The ocean color layer ranging from blue to orange depict air temperatures 2 meters (T2M) above sea level. Since Sea Surface Temperatures (SST) are typically measured at sea level and below, the T2M model output behaves somewhat differently. Nonetheless, it is a reasonable proxy to SST.

Landcover information is taken from the Next Generation Blue Marble dataset.

Sea Ice is depicted as solid white and clouds are shades of white.

The wind layer is depicted as flowing white arrows.

This project was developed in support of a hyperwall show titled "Pursuit of Light" which is scheduled to premiere on April 19, 2012 at the Smithsonian Uvar-Hazy Center during the space shuttle Discovery Transfer Ceremony on a Jumbotron. The hyperwall itself is a multi-screen display system that allows for the display of very high resolution images beyond current 1080p HDTV standards, allowing for much greater detail to be shown on much larger screens.

Sea Ice layer. Since the model run is in June, the sea ice is mostly concentrated closer to the North Pole and is only really seen at the beginning of the animation where more of the North Pole is in view.

Proxy Sea Surface Temperature (SST) layer. Colors ranging from blue to orange depict air temperatures 2 meters (T2M) above sea level. Since SSTs are typically measured at sea level and below, the T2M model output behaves somewhat differently. Nonetheless, it is a reasonable proxy for SST.

Hyperwall frames for the sample animation composite depicting winds, clouds, and temperature 2 meters above sea level. The names of the screens that comprise the hyperwall follow the spreadsheet convention in which rows are assigned numbers, beginning with 1 at the top, and columns are assigned letters, beginning with A at the left. The display in the upper left is A1. The display in the bottom right is E3 (for a 5 x 3 display).
