Cloud & Ice Nuclei
Bringing clarity to climate change and weather modification
Identifying atmospheric cloud condensation nuclei (CCN) and ice nuclei (IN) concentrations is critical for advancements in cloud physics, climate modeling, and accurately predicting the magnitude of global climate change. CCN and IN measurements also help weather modification operators determine when and where to seed clouds. With Droplet’s portfolio of ice and cloud nuclei instruments, you can:
Observe the conditions under which a particle will form a cloud or ice
Determine the particles that are active in cloud formation
Understand how pollution affects clouds, precipitation, and our climate
Explore the research applications
