The Atmosphere‐Space Interactions Monitor (ASIM) on the International Space Station (ISS) provides optical radiances and images of lightning flashes in several spectral bands. This work presents a lightning flash simultaneously observed from space by ASIM, the Geostationary Lightning Mapper (GLM) and the Lightning Imaging Sensor on the International Space Station (ISS‐LIS); and from ground by the Colombia‐Lightning Mapping Array (Colombia‐LMA). Volumetric weather radar provides reflectivity data to help to interpret the effects of the cloud particles on the observed optical features. We found that surges in radiance in the band at 777.4 nm appear to be related mostly with lightning processes involving currents as well with branching of lightning leaders with new leader development. In cloud areas with reflectivity <18 dBZ above the lightning leader channels at altitudes >7 km, these have been imaged by ASIM and GLM. But in the region with reflectivity <23 dBZ above the lightning leader channels, despite its lower cloud tops and similar altitudes of lightning channels, these have been almost undetectable. The calculated relative optical depths are consistent with the observed optical intensity at the cloud top. Despite the effects of the cloud particles and the altitude of the lightning channels on the attenuation of the luminosity, the luminosity of the lightning channels due to different processes is fundamental for the imaging of lightning from space.

通过ASIM，哥伦比亚雷电映射阵列，GLM和ISS-LIS同时观察雷电

国际空间站（ISS）上的“大气-空间相互作用监测器（ASIM）”提供了几个光谱带的光辐射和闪电图像。这项工作提出了由ASIM，对地静止闪电测绘仪（GLM）和国际空间站（ISS-LIS）上的闪电成像传感器同时从太空观察到的闪电；并由哥伦比亚雷电测绘阵列（Columbia‐LMA）从地面引出。体积气象雷达提供反射率数据，以帮助解释云颗粒对观测到的光学特征的影响。我们发现，在777.4 nm波段的辐射激增似乎主要与涉及电流的闪电过程以及随着新领导人的发展而产生的闪电领导人的分支有关。在云层中反射率< 在高度大于7 km的避雷针通道上方18 dBZ，这些已经由ASIM和GLM进行了成像。但是，在反射率低于雷电引导通道的区域小于23 dBZ的区域中，尽管其云顶较低且雷电通道的高度相似，但几乎无法检测到这些。计算出的相对光学深度与在云顶观测到的光学强度一致。尽管云粒子和雷电通道的高度对光度的衰减有影响，但是由于过程不同而导致的雷电光度对于从空间成像是至关重要的。尽管其云顶较低且闪电通道的高度相似，但这些几乎是无法检测到的。计算出的相对光学深度与在云顶观测到的光学强度一致。尽管云粒子和雷电通道的高度对光度的衰减有影响，但是由于过程不同而导致的雷电光度对于从空间成像是至关重要的。尽管其云顶较低且闪电通道的高度相似，但这些几乎是无法检测到的。计算出的相对光学深度与在云顶观测到的光学强度一致。尽管云粒子和雷电通道的高度对光度的衰减有影响，但是由于过程不同而导致的雷电光度对于从空间成像是至关重要的。
