There will be several referee systems utilized in order to produce the customer referee data packages. For aerosol releases, the primary systems used are the aerodynamic particles sizers (APS) and light detection and ranging (LIDAR). For vapor releases, the primary systems used are the Gasmet Gas Analyzer System and Chemical Cloud Tracking System (CCTS). Additional meteorological capabilities, such as Portable Weather Information Display System (PWIDS) and test grid meteorological towers will also be used.
