Radar coded message

From Glossary of Meteorology

radar coded message

The encoded and transmitted report of radar features observed by a WSR– 88D radar. The message consists of three main parts.

Part A contains a display and tabular listing of composite reflectivity data; the display may also contain annotations or graphical overlays generated by various radar algorithms. Part B contains a vertical profile of horizontal wind obtained from the velocity–azimuth display (VAD) algorithm. Part C contains the locations and characteristics of features automatically generated by radar algorithms (e.g., tornadic vortex signature, mesocyclone signature, storm centroid, storm top, and hail indices) as well as optional manual entries (e.g., precipitation type, height of melting level, location and movement of individual storms and tropical storms, and location of line echo wave patterns).
