Short summary

We present a new method for the absolute calibration of atmospheric radiance measurements. Existing methods are based on laboratory measurements, but our method uses the atmospheric radiance measurements themselves. For selected sky conditions these measurements are compared to radiative transfer simulations. The method is very accurate (better than 7%) and might be used for a variety of scientific applications, as well as for the determination of the energy yield of photovoltaic cells.
