IAGT (The Institute for the Applications of Geospatial Technology) has released a new plug-in for SERVIR Viz (a variation of WorldWind.net). Climate Mapper was developed for SERVIR Viz to give access to historical weather data as well as projections of climate change. Currently, the data is centered on Africa, but a global dataset is forthcoming.
You can download the plug-in here, it is a large download (108MB), that is because it includes the database of the data for offline viewing of the data. This plug-in is for SERVIR Viz, after talking to the developer there is now a WorldWind version but it needs approval for it to be released.
Edit: The WorldWind plug-in has been released.
When you download Climate Mapper and install it, you can access it from the task bar.
You will then get a new window where you can select a theme; Temperature, Precipitation, Soil Moisture, etc.. select if you want observed (historical) data or modeled data (future) and the date range to view.
You can then map the data to the WorldWind globe. This view shows the precipitation in Africa from 1961 to 1990.
You can also chart the data from a certain point by clicking the "Graph by X,Y Location" button and then clicking on the WorldWind globe. You will then get a graph of the data for that location which you can export for use outside of WorldWind.
