Have your students become citizen scientists! The NOAA National Severe Storms Laboratory is collecting public weather reports through a free app available for smart phones or mobile devices. The app is called “mPING,” for Meteorological Phenomena Identification Near the Ground. The app allows anyone with a smartphone to send in reports of large hail, damaging winds, low visibility, and other hazardous weather conditions. Reports on severe weather days can be extremely helpful in providing ground truth for the NWS our severe warnings.
