Aerosols and Solar Extinction



Desert Aerosols, Doha, Qatar – Click to enlarge

Aerosols directly and indirectly effect the Earth’s radiation budget and climate.  As a direct effect, aerosols absorb and scatter sunlight, affecting the spectral intensity of solar radiation reaching the earth’s surface.   As an indirect effect, atmospheric aerosols modify cloud formation processes and how clouds affect the energy budget.

Aerosol Animation

Aerosol Optical Depth (AOD) defines the degree to which aerosols prevent the transmission of sunlight by absorption or scattering.  AOD is measured using an integrated extinction coefficient over a vertical column of air.  The extinction coefficient can be used to analyze solar extinction and the performance of solar power systems as a function of location and time.

Solar Data Animation

A solar data animation is supplied to assess quality, spatial and time series dimensions:

  • The quality dimension is a function of the availability of different sunlight components: Global Horizontal Irradiance (GHI), Direct Normal Irradiance (DNI), and Diffuse Horizontal Irradiance (DHI).
