Description
The Coastal Zone Color Scanner Experiment (CZCS) was the first instrument devoted to the measurement of ocean color and flown on a spacecraft. Although other instruments flown on other spacecraft had sensed ocean color, their spectral bands, spatial resolution and dynamic range were optimized for land or meteorological use and had limited sensitivity in this area, whereas in CZCS, every parameter was optimized for use over water to the exclusion of any other type of sensing. CZCS had six spectral bands, four of which were used primarily for ocean color. These were of a 20 nanometer bandwidth centered at 443, 520, 550, and 670 nm. Band 5 had a 100 nm bandwidth centered at 750 nm and a dynamic range more suited to land. Band 6 operated in the 10.5 to 12.5 micrometer region and sensed emitted thermal radiance for derivation of equivalent black body temperature. (This thermal band failed within the first year of the mission, and so was not used in the global processing effort.) Bands 1-4 were preset to view water only and saturated when the IFOV was over most types of land surfaces, or clouds.

These files contain Digital Orthophoto files for the State of Virginia developed from imagery acquired in spring 2006 and 2007. In the spring of 2006, the Commonwealth of Virginia, through the Virginia Geographic Information Network Division (herein referred to as VGIN) of the Virginia Information Technologies Agency (VITA) contracted with the Sanborn Map Company to provide aerial data acquisition, ground control, aerotriangulation and development of statewide DTM and digital orthophotography. Approximately 15% of the State was acquired in the year 2006 and the balance in 2007. All data acquired in 2006 is jurisdiction based. The data acquired in 2007 includes overlap along the boundaries of jurisdictions captured in the previous year 2006. This ensures each jurisdiction has full coverage from either Year 2006 or 2007 without 'mixing' imagery vintage along the edge of a jurisdiction. The project encompasses the entire land area of the Commonwealth of Virginia. The State boundary is buffered by 1000'. Coastal areas of the State bordering the Atlantic Ocean or the Chesapeake Bay are buffered by 1000' or the extent of man-made features extending from shore. The entire State was intially designed to support 1"=200' (1:2400) scale mapping. Jurisdictions throughout the State were provided an option to upgrade to a 1"=100' (1:1200) map scale. All data development processes for the DTM conform to the ASPRS Draft Aerial Photography Standards (1995) and Model Virginia Map Accuracy Standards (1992), which generally follow the ASPRS Accuracy Standard for Large-Scale Mapping (1990) for relevant mapping scales. The DTM supports the creation of 6-inch or 1-foot map orthoimagery at the relevant scales.

Description
Access to High Performance Computing Capabilities Located at the ERDC Information Technology Laboratory in Vicksburg, Miss., the Department of Defense (DOD) Supercomputing Resource Center (DSRC) provides high performance computing (HPC) resources to DOD scientists and engineers across the Nation . The DSRC is responsible for operation and maintenance of supercomputing systems and the transfer of technical knowledge to DOD research projects. It typically operates two or more supercomputers on an average four-year life cycle. It also provides documentation, courseware, technical assistance, and project support for DOD scientists and engineers. A Competitive Advantage Many DOD projects require supercomputing capability to accomplish science and technology objectives. Supercomputing is used to predict the response of engineered systems in complex environments and to analyze patterns in physical systems. Supercomputing provides a technological advantage for DOD projects. It helps reduce defense system costs by shortening the design cycle and reducing reliance on expensive and destructive live experiments and prototype demonstrations. However, supercomputing technology is changing rapidly, and global competition is an increasing threat to technology leadership. The DSRC mission is therefore to continuously modernize supercomputing systems, ensuring a competitive advantage to DOD technology projects. Supercomputing Systems The Center's computing resources available at the end of 2012 include 1.8 peak PFLOPS of computing capability: a Cray XE6 with 9432 AMD 16 core 2.5-GHz Interlagos compute processors (150,912 cores) (1509 TFLOPS), 32GB dedicated memory per node, and 7200TB disk storage; an SGI Altix ICE 8200 with 1920 2.8-GHz dual quad-core compute processors (172 TFLOPS), 24GB of dedicated memory per node, and 721TB of disk storage; a Cray XE6 with 936 AMD 16 core 2.3-GHz Interlagos compute processors (14,976 cores) (138 TFLOPS), 64GB dedicated memory per node, and 140.4TB disk storage; and 15PB of local archival tape storage. Access to the Center's HPC systems is provided through the Defense Research and Engineering Network (DREN) to users around the Nation. User Support The DSRC provides a multi-tiered knowledge support system, anchored by a web presence, including documentation and user assistance in debugging, programming techniques, visualization, and data analysis methods. ERDC staff provides direct consultation to DOD projects, ranging from basic problem resolution (e.g., system access) to scientific computing support. The ERDC Data Analysis and Assessment Center ( DAAC) supports pre- and post-processing of large data sets. DAAC scientific visualization experts develop custom solutions for DOD projects, while also supporting many small projects through online consultation and training. The DAAC also provides conceptual visualization capabilities to complement the traditional data visualization techniques. These capabilities take advantage of industry-leading animation and modeling software, enabling DOD scientists to communicate all aspects of their research by setting their results in context. Success Stories Nanotechnology is the focus of many DOD projects seeking improvements in material properties. Molecular engineering is being used to develop high-performance infrastructure materials with five to 10 times the strength, strength-to-weight ratio, or stiffness-to-weight ratio of existing infrastructure materials. The ERDC Advanced Materials Initiative (AMI) is one DOD project using supercomputers to accelerate the development of new high-strength, low-weight materials. The AMI relies heavily on simulations and nanometer-scale experimental techniques to design and process new materials with nanometer-scale precision. One of the initial research efforts of the AMI program was to design and develop a laboratory sample of a 1 million psi carbon nanotube-based fiber. Through supercomputer simulations, researchers determined the effects of molecular defects on carbon nanotubes, which are the basic building blocks of the fiber. Carbon nanotubes with common molecular defects have greater than 1 million psi tensile strength, but fibers composed of aligned carbon nanotubes are far weaker. The project team therefore developed and evaluated new molecular designs with chemical bonds to strengthen the fibers. Atomistic modeling and molecular design allows researchers to discover, design, and test advanced materials before they are produced. This saves considerable amounts of time and resources over the traditional build-test, rebuild-retest cyclic method of material development. This project resulted in two Small Business Technology Transfer contracts to transfer this technology to the private sector to develop a commercially viable method for producing 1 million psi carbon nanotube-based fibers.

In 2002 and 2003, the U.S. Geological Survey (USGS), Woods Hole Coastal and Marine Science Center (WHCMSC), in cooperation with the National Oceanic and Atmospheric Administration (NOAA), conducted three exploration cruises (USGS Cruise 02051, NOAA RB0208, September 24 to 30, 2002; USGS Cruise 03008, NOAA RB0303, February 18 to March 7, 2003 and USGS Cruise 03032, NOAA RB0305, August 28 to September 4, 2003). These cruises mapped for the first time the morphology of this entire tectonic plate boundary stretching from the Dominican Republic in the west to the Lesser Antilles in the east, a distance of approximately 700 kilometers (430 miles). Observations from these three exploration cruises, coupled with computer modeling and published Global Positioning System (GPS) results and earthquake focal mechanisms have provided new information that is changing the evaluation of the seismic and tsunami hazard from this plate boundary. The observations collected during these cruises also contributed to the basic understanding of the mechanisms that govern plate tectonics, in this case, the creation of the island of Puerto Rico and the deep trench north of it. Results of the sea floor mapping have been an important component of the study of tsunami and earthquake hazards to the northeastern Caribbean and the U.S. Atlantic coast off the United States.

MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra (EOS AM) and Aqua (EOS PM) satellites. Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. Terra MODIS and Aqua MODIS are viewing the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths (see MODIS Technical Specifications). These data will improve our understanding of global dynamics and processes occurring on the land, in the oceans, and in the lower atmosphere. MODIS is playing a vital role in the development of validated, global, interactive Earth system models able to predict global change accurately enough to assist policy makers in making sound decisions concerning the protection of our environment.
