Aerosol optical properties over the Svalbard region of Arctic: ground-based measurements and satellite remote sensing
In view of the increasing anthropogenic presence and influence of aerosols in the northern polar regions, long-term continuous measurements of aerosol optical parameters have been investigated over the Svalbard region of Norwegian Arctic (Ny-Alesund, 79°N, 12°E, 8 m ASL). This study has shown a cons...

In view of the increasing anthropogenic presence and influence of aerosols in the northern polar regions, long-term continuous measurements of aerosol optical parameters have been investigated over the Svalbard region of Norwegian Arctic (Ny-Alesund, 79°N, 12°E, 8 m ASL).
