Microwave attenuation in rain at C-band. observed in radar data from Alberta. Canada. has been assessed by means of two different estimators one employing AD measured simultaneously by an S-band radar and the other a comparison of synchronized S- and C-band reflectivity measurements. While good agreement between the two has been found in some cases. in others the second method gave a larger estimate than the first by up to a factor of two. It is possible that the KDP method is underestimating the attenuation due to the assumption of a Marshall-Palmer drop size distribution which does not accurately enough represent the true drop size distribution present.
