Analysis of Blue Corona Discharges at the Top of Tropical Thunderstorm Clouds in Different Phases of Convection
Dimitriadou, Krystallia; Chanrion, Olivier; Neubert, Torsten; Protat, Alain; Louf, Valentin; Heumesser, Matthias; Husbjerg, Lasse; Köhn, Christoph; Østgaard, Nikolai; Reglero, Victor (Journal article; Peer reviewed, 2022)We report on observations of corona discharges at the uppermost region of clouds characterized by emissions in a blue band of nitrogen molecules at 337 nm, with little activity in the red band of lightning leaders at 777.4 ... -
First 10 Months of TGF Observations by ASIM
Østgaard, Nikolai; Neubert, Torsten; Reglero, Victor; Ullaland, Kjetil; Yang, Shiming; Genov, Georgi; Marisaldi, Martino; Mezentsev, Andrey; Kochkin, Pavlo; Lehtinen, Nikolai; Sarria, David; Qureshi, Bilal Hasan; Solberg, Arne Olav; Maiorana, Carolina; Albrechtsen, Kjetil; Budtz-Jørgensen, Carl; Kuvvetli, Irfan; Christiansen, Freddy; Chanrion, Olivier; Heumesser, Matthias; Navarro-Gonzalez, Javier; Connell, Paul H.; Eyles, Christopher J; Christian, Hugh J.; Al-Nussirat, Samer (Peer reviewed; Journal article, 2019)The Atmosphere‐Space Interactions Monitor (ASIM) was launched to the International Space Station on 2 April 2018. The ASIM payload consists of two main instruments, the Modular X‐ray and Gamma‐ray Sensor (MXGS) for imaging ... -
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 ... -
Observation of Blue Corona Discharges and Cloud Microphysics in the Top of Thunderstorm Cells in Cyclone Fani
Li, Dongshuai; Neubert, Torsten; Husbjerg, Lasse Skaaning; Zhu, Yanan; Chanrion, Olivier; Lapierre, Jeff; Luque, Alejandro; Köhn, Christoph; Heumesser, Matthias; Dimitriadou, Krystallia; Stendel, Martin; Kaas, Eigil; Olesen, Emilie Petrea; Liu, Feifan; Østgaard, Nikolai; Reglero, Víctor (Journal article; Peer reviewed, 2023)Blue corona discharges are often observed at the top of thunderclouds. They are bursts of streamers, but the cloud conditions that enable them are not well known. Here we present observations by the Atmosphere-Space ... -
Spectral Observations of Optical Emissions Associated With Terrestrial Gamma-Ray Flashes
Heumesser, Matthias; Chanrion, Olivier; Neubert, Torsten; Christian, Hugh J.; Dimitriadou, Krystallia; Gordillo-Vazquez, Francisco J.; Luque, Alejandro; Pérez-Invernón, F. J.; Blakeslee, Richard J.; Østgaard, Nikolai; Reglero, Victor; Köhn, Christoph (Journal article; Peer reviewed, 2021)The Atmosphere-Space Interactions Monitor measures Terrestrial Gamma-Ray Flashes (TGFs) simultaneously with optical emissions from associated lightning activity. We analyzed optical measurements at 180–230, 337, and 777.4 ...
