Input

 Planning Mode

 In the Planning Mode, CHARM software guides you through a list of scenarios that describe a particular release and the present meteorological conditions. The release and meteorology descriptions can be input via a summary sheeet or tabbed dialogs. To modifiy information on the summary sheet, double click on it.

When you select the Plume display, CHARM software requests a release time to use in the calculations. This enables a simulation of the release. The various graphic displays can be altered with a variety of options, and the release information can be stored in a scenario file for use with CHARM software's emergency response mode.

 Emergency Mode

 The potential release scenarios saved in the Planning Mode can be used in a real-time Emergency Response Mode. The scenarios are linked with icons on a map. You can define maps with the CHARM Editor for use in CHARM displays. With icons on a map, a user can define a release by point and click on a map. This capability makes graphical input available.

 In the Emergency Response Mode, CHARM software quickly accesses stored input and can combine that information with real-time meteorological data, if available, to give real-time predictions of where the impact is going. The CHARM software can be set up to start with a map/icon interface. The map icons can be selected to show release scenarios and other maps.

 CHARM software generates concentration, radiation, and overpressure footprint displays, plots, tables, and site information. In Emergency Mode the impacts are automatically updated as new meteorological data becomes available. Emergency response procedures for a particular chemical release, local sources of help, and important phone numbers stored in the planning mode can be retrieved quickly in the emergency response mode.
