Does the Solargis model account for dust and pollution in the air?

Yes, the Solargis model does account for dust and pollution in the air. To account for atmospheric aerosol content (haze, dust, particulate air pollutants, smoke, etc.) we make use of data from MACC-II project, which combines state-of-the-art atmospheric modeling on a global scale with Earth observation data.

It is, however, important to note that compared to satellite data, aerosol data (from MACC-II project) used in our model have lower spatial resolution and therefore cannot resolve local effects, especially in areas with extreme and changing concentrations. Therefore uncertainty of Solargis data can be higher in regions with high industrial pollution.

Where possible we try to enhance the quality of aerosol inputs used in our model. For example, we also make use of aerosol measurements from the AERONET network of ground-based aerosol measurement stations. On-site measurements of GHI and DNI can also be used to improve the accuracy of Solargis data in regions with high air pollution.
