World Weather Tracker captures global or local weather data on an around the clock fashion. Easy to use, you can view today's weather graphics or last years, and export them into AVI files. But, weather data isn't the only thing you can keep track of, pretty much any image that exists on the Internet. WWT focuses on local and global weather and some space data, but virtually you can track anything on an easy to use environment. Data is organized and stored, so it makes it easy to go back to a date and review the data collected. You can also overlay images, use transparencies, replace colors, and define colors and what they mean so that, with a click of a mouse you can easily identify features in the data. Create your own movie clips of data collected; manipulate the output by manipulating colors and adding overlays.
