PECAN

Plains Elevated Convection At Night (PECAN)

PECAN is a large meteorology experiment sponsored by the National Science Foundation (NSF), the National Oceanic and Atmospheric Administration (NOAA), National Aeronautical and Space Administration (NASA), and the Department Of Energy (DOE). The scientific goal of the project is to collect data before and during nighttime severe storms in order to learn how they form, why some become severe, and how to predict them better.

NASA has joined a multi-agency field campaign studying summer storm systems in the U.S. Great Plains to find out why they often form after the sun goes down instead of during the heat of the day.
