Clouds Clouds have a large influence on weather and climate, but many processes regarding cloud evolution and formation of precipitation are still poorly understood. At SRON we work on improved remote sensing of cloud properties, such as droplet sizes, droplet concentrations and whether cloud tops consist of liquid droplets or ice crystals. I am particularly…

The SPEX airborne measurement instrument has flown in 2017, 2020 and 2024 during the ACEPOL, SCARBO and PACE-PAX flight campaigns. Aboard a NASA research aircraft, SPEX airborne measures properties of aerosols-fine dust such as soot and ash-from an altitude of 20 kilometres. To do this, it determines the polarisation of sunlight for each colour after…

SRON’s aerosol instrument SPEX airborne is spreading its wings again. In early October it will start a series of measurement flights across Europe onboard a Falcon-20 research aircraft. SPEX airborne will measure aerosols in the atmosphere—tiny dust particles that can disrupt measurements of the greenhouse gas CO2. In time, SPEX is intended to go into space…
