“…The next‐generation of geostationary satellites that includes the Geostationary Operational Environmental Satellite–R (GOES‐R) with Geostationary Lightning Mapper (GLM) sensor [ Goodman et al ., ] and the Meteosat Third Generation (MTG) with Lightning Imager (LI) sensor [ Stuhlmann et al ., ] will map total lightning activity continuously day and night with near‐uniform spatial resolution of 8 km, frame rate of 2 ms, and a product latency of less than 20 s for GLM. The refinement of our current understanding about the processes relating cloud microphysical signatures and lightning density could be very useful for several applications, such as data assimilation [e.g., Fierro et al ., , ; Mansell , ; Qie et al ., ], nowcasting [e.g., Goodman et al ., ; Schultz et al ., , , ], and rainfall estimation [e.g., Soula , ; Wang et al ., ; Xu et al ., ].…”
