FT-IR analysis of aerosols in microgravity

open access: green
Aerosol evolution is a major challenge in climatology. Many questions remain unanswered, especially in the field of cloud microphysics. The aerosols studied here consist of micrometric water droplets formed from a mixture of water-saturated air and HFE7100, and are studied using a set-up that combines optical microtomography and Fourier transform ...
