Short summary

A new photometer for continuous measurements of aerosol light absorption coefficient is described, optimized for long-term studies of the climate-forcing properties of aerosols. The device is small, sensitive, precise, and simple to operate. It is suitable for long-term measurements at remote locations and is currently in operation at about two dozen sites worldwide.
