The purpose of this SAE Aerospace Standard is to provide guidelines for the components and configurations that define the research and commercial versions of the Weather Support to Deicing Decision Making (WSDDM) winter weather nowcasting system. This revision has resulted in two major modifications and several minor modifications. The major modifications to this document include the removal of mention of the Vaisala AviCast system and standardization on the terminology referring to the precipitation gauges used in the WSDDM system. Vaisala has stated they will no longer be marketing, maintaining, or supporting their AviCast system and have shut down their AviCast operations. The wording regarding the precipitation gauges has also been standardized in the document and instances of “snow gauge” and “all-weather precipitation gauge” are now simply referred to as “precipitation gauge”. Further clarification of what is meant by “precipitation gauge” has been added to section 8 and updated information regarding the specific precipitation gauges (including URLs and contact information for the associated companies) has been added. This section also now states that tipping bucket precipitation gauges should not be used with this system due to the established problems with using those gauges in winter conditions. Other modifications to the document include grammatical improvements, new publication references, rates expressed in both mm/h and g/dm2/h, updated figures, updated computer system requirements, and updated maintenance needs for the sensors.
