Aerosols
Tiny particles with a big environmental impact
Scientists are continually working on ways to understand the impact of natural and human-made aerosols on our climate – from scattering sunlight back into space to aerosol-cloud interactions that impact the properties of clouds. Yet aerosols are one of the most uncertain aspects in cloud formation, persistence, and dissipation. Droplet helps scientists to close the gap of uncertainty through measurements, modeling, and publications, with instruments that enable:
Collection of real-time aerosol size distributions in either ground/cabin-based or aircraft-based instruments to captures information on quickly changing air masses
Single particle specificity and resolution to reduce uncertainty in calculations with differentiation between more particle sizes
