Abstract. 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 and specifically tailored to modern instruments such as the Modular Multispectral Imaging Array (MMIA) component of the Atmosphere-Space Interactions Monitor (ASIM) that operates from the International Space Station. In this article we describe the algorithms implemented in the code and discuss several applications and examples, with an emphasis on the interpretation of MMIA data.

Short summary
Lightning flashes are often recorded from space-based platforms. Besides being valuable inputs to weather forecasting, these observations also enable research into fundamental questions in lightning physics. To exploit them it is essential to understand how light propagates from a lightning flash to a space-based observing instrument. Here we present an open-source software tool to model this process that extends previous works and overcomes some of their limitations.
