The WSMR clear, dry weather provides an excellent test environment for optical, electro-optical and infrared sensors. WSMR Meteorological assets can accurately characterize the atmospheric test environment. The Army Research Lab tenant organizations at WSMR can provide survivability, lethality, vulnerability and atmospheric effects services for sensor systems tests. The Center for Countermeasures (CCM), a WSMR tenant, provides a wide range of countermeasures and counter-countermeasures analysis, test and evaluation services. The CCM can also provide signature characterization of potential targets.
