N2 - 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 Interactions Monitor on the International Space Station, we find that their distribution in rise time falls into two categories. One with fast rise times of 30 mu s or less that are relatively unaffected by cloud scattering and emanate from within similar to 2 km of the cloud tops, and another with longer rise times from deeper within the clouds. 50% of cells generating shallow events are associated with overshooting tops compared to 34% of cells generating deeper events. The median Convective Available Potential Energy of the cells is similar to 70% higher for the shallow events and similar to 38% higher for the deeper events than for lightning cells, suggesting the discharges are favored by strongly convective environments.
