The radiative forcing of atmospheric aerosols represents one of the largest uncertainties in the Earth radiative budget. Global networks of surface based sunphotometers such as the GAWPFR network operated by PMOD/WRC measure the aerosol optical depth at several distinct wavelength channels between the ultraviolet and the infrared. A precision solar array spectroradiometer has been developed in order to complement and eventually replace the four-channel precision filter sunphotometer currently in use.

CHARADMexp campaign is funded by the European Space Agency.
CHARADMexp is supported by the BEYOND Centre of Excellence, in the frame of the satellite cal/val activities performed by the Centre. LIVAS climatology as well as the smoke dispersion and dust services provided by BEYOND will be validated through the CHARADMexp campaign.
ACTRIS provides support to CHARADMexp participants by offering access to the Finokalia research facilities through the Transnational Access activity of the Network.
