A model is presented for the depletion of incoming solar insolation by an atmosphere with a stratus overcast. In the clear air above the clouds, the depletion has been accounted for by a scattering-absorption model due primarily to London (10). Within the cloud, a spectrally averaged absorption coefficient for liquid water drops is devised. The effect of this absorption coefficient is to bring about abnormally high values of absorption. These absorption values are then reduced to account for scattering, similar to a non-absorbing scattering theory by Fritz (4). Tests of the solar-depletion model were made by comparison with pyrheliometer data recorded under stratus overcast conditions at Pacific Grove, California, during the summer of 1964.
