Echo top height is a volume product that originates from the NWS WSR-88D NEXRAD Doppler radars. These are the same network of radars that is used to build the familiar radar image pilots readily use in the cockpit. The echo top height product, however, is arguably the most misused data that is broadcast to your satellite-based weather receiver. Despite what many pilots are taught, this product does not represent the height of the cloud tops and should never be used as such since it is often likely to produce unreliable and inconsistent results. In this workshop we will examine a case where echo top heights demonstrated the potential for pockets of deep, moist convection even in locations where cloud top heights were actually well below the freezing level.
