We would like our participants to: Provide feedback on the ability of these applications to enhance traditional base-radar data analysis in warning decision making. Suggest improvements or new multiple-radar/sensor products that will aid warning decision making. Receive an introduction to the new products, after which the products will be available (via Google Earth) to use in operations after the participants return to their forecast offices.
