The complexity of Atmospheric Transport and Dispersion (ATD) modeling requires physically consistent weather data evolving in both space and time. Spatially and/or temporally averaged data found in climatological products is not suitable for ATD modeling. The proposed solution for providing “typical day” meteorological data couples innovative search techniques applied to long-range historical ...

Atmospheric and Environmental Research, Inc. proposes to develop a prototype threat-reduction system for the dispersion of a weapons-of-mass destruction warhead in the upper atmosphere. Our system will extend current DTRA atmospheric transport and dispersion capabilities into the 20-120 km altitude region. This will be accomplished using a combination of a zonally-averaged transport model of the s ...

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 ...

U.S. forces working in low-level radiation environments have unsatisfactory choices for monitoring radiation exposure. A solid-state photomultiplier (SSPM) uses an array of silicon based avalanche photodiodes (APD) to collect light and produce a signal proportional to the amount of light collected. The ability to produce arrays of APD’s in a CMOS (Complimentary Metal Oxide Semiconductor) envir ...

The proposed muti-mode imaging system will allow a combination of X-ray Backscatter imaging (proven successful in finding IEDs in AS&E's Z Backscatter Van) and other sensor modalities, such as vapor/trace detection and video, to be mounted on a robotic platform(the iRobot R-Gator) such that the system can be quickly moved into location to examine a potential threat, including WMD dispersal devices ...

We propose to develop a forward-deployable, three-dimensional visualization capability suitable for incorporation into web-based, next-generation consequence assessment models, such as the Joint Effects Model (JEM) and the Integrated Weapons of Mass Destruction Toolset (IWMDT). The thin-interface, web-based, image-server visualization model will enable more informed decisions by the consequence as ...

Strategic DoD satellite and missile systems (Space Based Radar, Space Tracking Surveillance Systems) operate in harsh radiation environments, and will be increasingly based on novel sub-100-nm semiconductor technologies and highly complex circuits. To ensure interruption-free operation, accurate prediction of the radiation response of these technologies and circuits is critical. Predictive calcula ...

We propose to improve the accuracy and capability of Numerical Weather Prediction (NWP) and Atmospheric Transport and Dispersion (ATD) models by performing a tight, downscale/upscale coupling of a community NWP forecasting system, WRF, with a special purpose, urban-to-microscale Computational Fluid Dynamics (CFD) model. This new capability addresses “bridging the gap” between the mesoscale and ...

We propose to develop a capability to correct and calibrate intra-urban sited meteorological stations data for subsequent use by NWP, ATD and force protection models. This new capability will provide a number of related innovations, including: a standalone software capability to assist in the siting of meteorological stations in urban areas; the development of sensor-centralized vertical profiles ...

This proposal utilizes our experience with the design and use of high energy density pulsed capacitors to demonstrate the feasibility of high energy density metallized film capacitors that meets the requirements for an x-ray simulator capacitors. This work extends our success with designing high energy density capacitors for other high current pulsed discharge applications by trading off energy de ...
