Researchers in Oklahoma, Nebraska, and Kentucky will study physics in the Earth's lower atmospheric boundary layer using small, easy-to-deploy unmanned airborne systems. In this illustration, a UAS known as MARIA (Meteorological Analysis Research Investigation Aircraft) flies into a developing weather system. Very little data exists on thunderstorm development--particularly supercells. This research will provide meteorologists with the data they need to increase tornado prediction time. Oklahoma State University is the lead institute for this project.
