    • Blue Flashes as Counterparts to Narrow Bipolar Events: The Optical Signal of Shallow In-Cloud Discharges 

      Li, Dongshuai; Luque, Alejandro; Gordillo-Vázquez, F.J.; Liu, Feifan; Lu, Gaopeng; Neubert, Torsten; Chanrion, Olivier; Zhu, Baoyou; Østgaard, Nikolai; Reglero, Víctor (Journal article; Peer reviewed, 2021)
      Narrow Bipolar Events (NBEs) are powerful radio emissions from thunderstorms, which have been recently associated with blue optical flashes on cloud tops and attributed to extensive streamer electrical discharges named ...

    • Modeling lightning observations from space-based platforms (CloudScat.jl 1.0) 

      Luque, Alejandro; Gordillo-Vázquez, Francisco José; Li, Dongshuai; Malagón-Romero, Alejandro; Pérez-Invernón, F. J.; Schmalzried, Anthony; Soler, Sergio; Chanrion, Olivier; Heumesser, Matthias; Neubert, Torsten; Reglero, Victor; Østgaard, Nikolai (Journal article; Peer reviewed, 2020)
      We describe a computer code that simulates how a satellite observes optical radiation emitted by a lightning flash after it is scattered within an intervening cloud. Our code, CloudScat.jl, is flexible, fully open source ...

    • Multi-Pulse Corona Discharges in Thunderclouds Observed in Optical and Radio Bands 

      Li, Dongshuai; Luque, Alejandro; Lehtinen, Nikolai Grigorievich; Gordillo-Vázquez, F.J.; Neubert, Torsten; Lu, Gaopeng; Chanrion, Olivier; Zhang, Hongbo; Østgaard, Nikolai; Reglero, Víctor (Journal article; Peer reviewed, 2022)
      How lightning initiates inside thunderclouds remains a major puzzle of atmospheric electricity. By monitoring optical emissions from thunderstorms, the Atmosphere-Space Interactions Monitor (ASIM) onboard the International ...

    • Observations of Blue Corona Discharges in Thunderclouds 

      Husbjerg, Lasse Skaaning; Neubert, Torsten; Chanrion, Olivier; Dimitriadou, Krystallia; Li, Dongshuai; Stendel, Martin; Kaas, Eigil; Østgaard, Nikolai; Reglero, Victor (Journal article; Peer reviewed, 2022)
      Blue electric streamer discharges in the upper reaches of thunderclouds are observed as flashes of 337.0 nm (blue) with faint or no emissions of 777.4 nm (red). Analyzing 3 years of measurements by the Atmosphere-Space ...

    • Optical emissions associated with narrow bipolar events from thunderstorm clouds penetrating into the stratosphere 

      Liu, Feifan; Lu, Gaopeng; Neubert, Torsten; Lei, Jiuhou; Chanrion, Olivier; Østgaard, Nikolai; Li, Dongshuai; Luque, Alejandro; Gordillo-Vázquez, Francisco J.; Reglero, Victor; Lyu, Weitao; Zhu, Baoyou (Journal article; Peer reviewed, 2021)
      Narrow bipolar events (NBEs) are signatures in radio signals from thunderstorms observed by ground-based receivers. NBEs may occur at the onset of lightning, but the discharge process is not well understood. Here, we present ...
