Short summary

Subvisual microscopic particles in the atmosphere are needed to act as seeds for cloud droplets or ice crystals to form. The microscopic particles, called ice-nucleating particles (INPs), form ice crystals and are rare, and their properties are not well understood, in part because measuring them is challenging and time consuming, and to date has not been automated. Here, we present the first online instrument that can continuously and autonomously measure INP concentration at 243 K.
