The research of the Aerosol Group of the ESRL Global Monitoring Division focuses on the relationship of aerosol optical and cloud droplet properties to radiative forcing and climate change. Our primary concern is studying how atmospheric particles alter the solar radiation at the Earth’s surface and at the top of the atmosphere via direct scattering and absorption or by cloud droplet formation. Our scientific questions probe how the aerosol properties change with composition, size, water uptake, cloud processing and transport. The work involves the design, testing and deployment of aerosol and cloud droplet instruments for field measurements and processing and analyzing the data from many field sites. Long term measurements are a core part of our program and allow us to observe changes in the aerosol properties on a seasonal basis and over a decade for some sites. These studies are complemented by short field programs with intensive operations and instrumentation that allow a detailed, synergistic analysis.
