The project consists in using a small package of heritage and novel sensors to sample the stratospheric air from a balloon platform and make measurements of aerosol size and concentration. These aerosols, which typically form in the tropics from natural and anthropogenic sources such as volcanic eruptions, play an important role in climate change by scattering sunlight away from the Earth. These measurements will support the scientific record of such observations and be highly useful for validating remote sensing measurements from satellites and other scientific instruments used during stratospheric balloon flights.
