Editorial for the Special Issue "Advances in Atmospheric Electricity".

In the last decades, important advances in lightning detection, lightning climatology, and the most fundamental physical and chemical mechanisms related to lightning have contributed to setting the role of lightning in the Earth's climate system. Thunderstorms with normal charge structures produce more negative than positive cloud-to-ground lightning, while positive cloud-to-ground lightning is more frequent in inverted polarity thunderstorms. However, there are still significant open research questions related to atmospheric electricity, such as the role of meteorology in the occurrence of lightning, the role of lightning in the ignition of wildfires, and how to improve lightning detection systems to monitor lightning discharges better.
