NASA World Weather, the largest 3D interactive platform for geospatial data visualization. How to use the application? To begin, go to the Available Layers tab in the top left corner.

Here, you can choose from different data sources, organized as Space, Weather, Academic, and Government.

1. Select a layer by either typing its name, or by navigating through the drop-down menu. Use the Selected Layers tab to change the order by which the layers are stacked on the globe.

2. Use the up and down arrows on each layer to move it; the topmost layer in the list is the outermost layer on the globe. Click on a selected layer to hide it, and click on one of the base layers to switch the innermost layer to it. From the Layer Controls tab, you can view all the legends for the layers you have selected.

3. You can view a layer independently by clicking on the View button. You can also change the date and time for a layer, and it will update on the globe accordingly. Change the opacity of a layer to make it more transparent and you’ll be able to see the interaction between stacked layers.

4. From the View Options tab, you can change the projection of the globe by selecting it from the drop-down menu. You can also navigate to a certain location; here we will navigate to the NASA Ames Research Center.

5. A pin will be placed in every location that you search for, by clicking on the globe icon in the top right corner, you can switch to the 2 globes mode. To demonstrate the value of this mode, let’s say you’re interested in studying the relationship between soil moisture, wind direction, and wildfires.

6. After adding the layers you need, go to the Selected Layers tab, modify your base layer if needed, and then click on the globe icon to move that layer between globes. You can see the Active Fires layer is now on the right globe.

7. From the Layer Controls tab, change the time of all layers to match each other.

8. To study the relationship, we can zoom in on an area with a large number of fires. By zooming in on a particular area, the resolution of all layers increases automatically, allowing you to see finer details and try to establish relationships and correlations visually.
