Abstract: Observations from the National Aeronautics and Space Administration Optical Transient Detector (OTD) and Tropical Rainfall Measuring Mission (TRMM)-based Lightning Imaging Sensor (LIS) are analyzed for variability between ...

Abstract: In some Florida thunderstorm cells, impulsive very high frequency (VHF) radiation from lightning channels begins abruptly in a layer that is typically 3?6 km in diameter, 1?3 km tall, and initially located just above the ...

Abstract: round-based lightning detection systems geolocated 877 terrestrial gamma ray flashes (TGFs) from a sample of 2,279 TGFs detected with the Fermi Gamma Ray Burst Monitor (GBM). From these accurate geolocations, 24 TGFs are ...
