Short summary

There is a natural and globally occurring layer of small droplets (aerosols) at roughly 20 km altitude in the atmosphere. In this work, the size of these droplets is calculated from satellite measurements for the years 2002 to 2005, which is important for the aerosol cooling effect on Earth's climate. These years are interesting because there were no large volcanic eruptions that would change the background state of the aerosols. The results are compared to reliable balloon-borne measurements.
