The objectives for the SCAR mission are to advance our knowledge of how the physical, chemical and radiative processes in our atmosphere are affected by sulfate aerosol and smoke from biomass burning; to improve our expertise at remotely sensing smoke, water vapor, clouds, vegetation and fires; and to assess the effects of deforestation and biomass burning on tropical landscapes. The SCAR-A campaign occurred in western Atlantic Ocean.

This data set consists of observations made with the CAR instrument and includes values for bidirectional reflectance factor at varying spectral bands.
