Clouds are shown as shades of white and ice is shown as shades of blue. Cloud and ice data from the model are volumetric, so a volumetric rendering technique called ray-casting was used to create the images. Winds are represented by moving arrows. Each of these data sets were from simulations at 3. 4 km per grid cell every 5 minutes for the East coast near where Isabel made landfall.This is a top-down view of the storm that was rendered in layers. There are layers (with alpha channels) for the dates, winds, clouds, and background. This allowed for editors to control when each of the elements was faded in during post production. A composited example is included. The layers should composited in the order listed above.This visualization was created in support of a video about the Climate in a Box project for the Fall 2009 American Geophysical Union (AGU) conference. || ", "release_date": "2009-12-11T00:00:00-05:00", "update_date": "2024-06-23T22:01:41.896696-04:00", "main_image": { "id": 495122, "url": "https://svs.gsfc.nasa.gov/vis/a000000/a003600/a003666/background.jpg", "filename": "background.jpg", "media_type": "Image", "alt_text": "Isabel background layer only", "width": 1280, "height": 720, "pixels": 921600 }, "main_video": { "id": 495099, "url": "https://svs.gsfc.nasa.gov/vis/a000000/a003600/a003666/comp_wind_cloud02.mp4", "filename": "comp_wind_cloud02.mp4", "media_type": "Movie", "alt_text": "Composited version of Isabel clouds+wind+dates+background", "width": 1280, "height": 720, "pixels": 921600 }, "main_credits": { "Visualizations by": [ { "name": "Greg Shirah", "employer": "NASA/GSFC" } ] }, "progress": "Complete", "media_groups": [ { "id": 353899, "url": "https://svs.gsfc.nasa.gov/3666/#media_group_353899", "widget": "Basic text with HTML", "title": "", "caption": "", "description": "This visualization shows cloud and ice data from an atmospheric simulation using the Weather Research and Forecasting (WRF) Model.
