Every five minutes XM-delivered satellite weather broadcasts the latest composite reflectivity mosaic that includes returns from both the NWS NEXRAD Doppler radars and Doppler weather radars from Environment Canada. The general goal is to provide the cleanest radar image possible allowing the pilot to determine where the most significant weather is located. On most days, the resulting mosaic is fairly accurate thanks to an algorithm that filters out “false” or non-precipitation returns. In this workshop, we will see what happens when proper filtering does not occur specifically with Canadian radar leaving areas of precipitation that often resemble deep, moist convection or thunderstorms.
