Last summer, I blogged about a storm classification algorithm that we were developing. We have now implemented it in real-time and one of my colleagues has added its output to our publicly available set of experimental products.
You can view the storm classification product in real-time with Google Earth -- the images are from moments ago, over the ocean, off the North Carolina coast. The four categories you'll see are N for not-organized, P for pulse storms, S for isolated supercells and L for quasi-linear convective storms. With each storm, you also get a few diagnostic parameters:
Here's are the links (you need Google Earth in order to view these):
