DTRA uses high-resolution mesoscale forecasts to drive HPAC, the DTRA dispersion modeling tool that generates critical forecasts of dosage resulting from releases of chemical, biological, or radiological agents. HPAC is designed to provide probablistic information based on estimates of the uncertainty of the input forecast fields of the meteorological variables (wind, temperature, etc.). ...

Hydrogen peroxide formation represents a loss of gas phase HOx and results in the transfer of atmospheric oxidative capacity to the liquid phase. Measurements of formaldehyde and H2O2 are vital to fully elucidate the atmospheric mechanisms associated with ozone formation and the formation of inorganic and secondary organic aerosol throughout the atmosphere. Tunable infrared differential absorpti ...

The optimal design for a rapidly-deployable, airborne HAB identification sensor requires the determination of the minimum spectral, spatial, dynamic range, and deployment capabilities necessary to achieve the goal of operational detection. This sensor must be capable of rendering a positive identification, with a low false alarm rate, in optical shallow waters, where the bottom is visible in the ...

U.S. forces working in low-level radiation environments have unsatisfactory choices for monitoring radiation exposure. The currently available A/UDR-13 pocket dosimeter is able to meet sensitivity requirements, but is cost prohibitive at ~$400 per unit, and it fails in the high temperature environments faced our military. Careful monitoring and accurate reporting of the exposed dose will reduce t ...

Proliferation of the weapons of mass destruction such as nuclear weapons is a serious threat in the world today. Prevention of the spread of nuclear weapons has reached a state of heightened urgency in recent years, especially since the events on September 11, 2001 and its aftermath. Gamma ray spectrometers are an important tool in checking the proliferation of the nuclear weapons. Important re ...

Conventional weapons rely on blast and fragmentation as the primary defeat mechanism, whereas non-energetic payloads rely on other means to defeat the target. Non-energetic weapons may defeat targets by the dispersion of aerosols (solid or liquid) or gases to interact with critical target elements. The objective is to cause some combination of denial, disruption, degradation, or destruction witho ...

We propose to demonstrate the ability to non-evasively probe the characteristics of material properties using acoustical waves through thermal conversion of a remote laser pulse. The advantages of proposed system as an inspection and identification technique are: 1) Non-contact: Sensor does not require contact with container 2) Stand-off: Sensor could be located many meters away from container 3 ...

Detector Technology will develop and manufacture a 10cm2 large format cone. The cone will be based on a ceramic substrate then coated with glass frit. The cone will then be attached to a standard single channel multiplier. Detector Technology will also investigate different low work function coatings to improve the first strike statistic of fluorescence. Simultaneous research in conjunction with s ...

Discontinuous graphite fiber reinforced aluminum magnesium matrix composite with microscopically dispersed add-on oxidizer coating is proposed for the application of enhanced lethality munitions. The composite with the coating is light-weight and reactive, which will generate high reaction temperature and a large amount of reaction heat. The composite also has sufficient mechanical strength for ...

We aim to develop analytic tools and instruments to improve performance predictions for photovoltaic power systems on buoys. Using these capabilities, we can design more powerful and reliable power systems and provide NDBC more power to operate offshore data buoys and serve the Nation with enhanced observations of the marine environment. Present day buoy power systems are feasible because they u ...
