The disadvantage, he said, is that the image shows the worst conditions in the atmosphere and goes back five minutes. "It overstates the negative, but we prefer to err on the side of too much rather than too little." WxWorx claims to be the only weather vendor that processes the Nexrad data using its own algorithms. According to Baron, by processing the data itself, WxWorx is able to provide better information about the weather. The government weather service, he said, processes the data at the end of the volume scan, "but we're processing it as we go. As we get each level we're looking at specific things. For example, looking at things like hail or tornados can be processed earlier by not waiting for the end of the scan. We like to think ours [algorithms] are better, but maybe it's conjecture." Each of the composite images, combining all of the cuts from each of the 142 radars that make up the Nexrad array, are put together to form a mosaic that allows a seamless image to be displayed in the cockpit. The resolution of the display is made up of blocks that are two kilometers square or about a mile square. In other words, any precipitation that the radar detects in that two kilometer block of airspace will be shown, at its greatest intensity, to fill the entire block.
