Volume-Rendered Global Atmospheric Model: Photorealistic Rendering

Visualizations by Greg Shirah Released on March 3, 2015

This is a photorealistic rendering of clouds using GEOS-5 model data. The camera is looking westard - from above the Pacific Ocean towards Asia. A simulated typhoon is visible near the center.

This visualization shows an attempt at creating a photorealistic view of the Earth based on data from NASA's Goddard Earth Observing System Model, Version 5 (GEOS-5). This particular model run, called 7km GEOS-5 Nature Run (7km-G5NR), spanned 2 years of simulation time at 30 minute intervals, but only a single timestep was used for this visualization. Each voxel of the 3d volume of data contains numerous physical parameters are available such as temperature, wind speed and direction, pressure, humidity, etc. This visualization uses a combination of the CLOUD and TAUIR parameters.

The goal of this animation was to make a realistic looking Earth using the GEOS-5 data. The height is exaggerated 4 times.

Data Used:

GEOS-5 Atmospheric Model on the Cubed-Sphere also referred to as: GEOS-5 Cubed-Sphere

Model - NASA GMAO

The model is the GEOS-5 atmospheric model on the cubed-sphere, run at 14-km global resolution for 30-days. GEOS-5 is described here http://gmao.gsfc.nasa.gov/systems/geos5/ and the cubed-sphere work is described here http://sivo.gsfc.nasa.gov/cubedsphere_overview.html.
