Visible Satellite, Radar Precipitation, and Cloud-to-Ground Lightning Convective Initiation Nowcasting for Aviation PI: John R. Mecikalski GOES Satellite-based 0-1 hour forecasts predict convective thunderstorm and first-flash lightning initiation. Used by Flight Control Centers to guide airline traffic. Working to provide enhance lead times of lightning occurrence, for airport operations. New work using European data in preparation for GOES-R (~2016).
