Abstract: Work has begun on a software suite that will automate the extraction of weather impacts information on artillery. By combining the information provided by the Battlescale Forecast Model and the Atmospheric Sounding Program with a rule base of thresholds for artillery systems, the user will be able to see either a text display of the effectiveness of a given artillery system or a map overlay demarcating the degree of effectiveness of a particular artillery system. This concept has been developed in software before as the Integrated Weather Effects Decision Aid (IWEDA); however, the application was for a much broader array of military systems as well as personnel. IWEDA has a rule for "artillery"; however, it is generic. Weather Effects on Artillery (WEA) will focus on three specific artillery systems initially: Sense & Destroy Armor (SADARM), Brilliant Anti-Tank (BAT), and Multiple-Launch Rocket System (MLRS). Included in the rule base will be systems used in tandem with artillery such as laser designators. In the alpha version of WEA, 26 rules will be instituted that will reference meteorological parameters including target-area winds, cloud base, precipitation type, winds aloft, * turbulence, temperature. IWEDA uses the Joint Mapping Toolkit (JMTK) for its map overlays. WEA will use the Geographic Resources Analysis Support System (GRASS), a very mature geographic information system for the overlay of contours delineating artillery effectiveness information.
