Nitrous Oxide (N20) flux is the net rate of nitrous oxide exchange between an ecosystem and the atmosphere. Data of this variable were generated by the USGS LandCarbon project using the General Ensemble Biogeochemical Modeling System (GEMS) based on modelled Land-Use/Land-Cover data and selected IPCC emission scenarios. The spatial extent is the conterminous United States and the temporal extent is from 1992 through 2050. Units of measure are expressed in g N2O/m2/yr. Data are projected to Albers Equal Area in the NAD83 datum at a resolution of 2000 meters and are spatially gridded in GeoTiff format.

This file contains the Radiometric camera-by-camera Cloud Mask dataset. It is used to determine whether a scene is classified as clear or cloudy. A new parameter has been added to indicate dust over ocean. This version of the ESDT is used by MISR PGE 13. (Suggested Usage: The RCCM is used during geophysical parameter retrievals. In the TOA/Cloud Product,RCCM is combined with stereoscopically derived cloud mask to 1) establish values of the Reflecting Level Reference Altitude,2) determine how a scene is classified for choosing angular integration coefficients for establishing TOA albedos,and 3) calculate regional scene classifiers. Retrieval of Aerosol/Surface Product properties requires the abscence of clouds,for retrieval assumptions to be valid.)

Comprehensive Environmental and Structural Analyses The ERDC Pavement Testing Facility, located on the ERDC Vicksburg campus, was originally constructed to provide an area protected from precipitation that allows for the construction and traffic testing of full-depth pavement sections. Today, the facility's pavement testing capabilities include innovative technologies, sophisticated instrumentation and accelerated trafficking equipment that help researchers in ERDC's Geotechnical and Structures Laboratory (GSL) perform comprehensive evaluations of important real-world pavement conditions. Covered Test Area Limits Exposure for Accurate Testing The ERDC Pavement Testing Facility has the space to allow for construction, trafficking and analysis of several test sections simultaneously. The facility houses offices and space for the facility manager, two instrumentation technicians, equipment storage, tool room, and instrumentation data acquisition room, as well as adequate space for parking construction equipment and load carts, and storing test section-specific construction materials. The facility has a maximum ceiling height of 50 feet, with a length of 375 feet and 145 feet in width. This facility provides a large covered area for test sections. This limits exposure to sunlight and isolates test sections from inclement weather. As a result, soil moistures - a critical parameter in pavement strength and performance - can be controlled. Vehicle Simulators Aid Load-Bearing Traffic Tests The facility is also home to one of the largest Heavy Vehicle Simulators-Aircraft (HVS-A) in the world. The HVS-A can operate off a high voltage electrical connection (available in the facility) or independently using its onboard diesel engine power plant. In addition, for test section evaluations, the HVS-A can: Fit almost any tire or wheel set required for trafficking simulations Simulate wheel loads up to 100,000 total pounds, varying from a heavy truck to fully-loaded cargo plane Apply wheel traffic in a channelized path or in a custom-programmed wander pattern Produce up to 500 passes per hour, running 24 hours a day if needed The HVS-A is also equipped with insulated removable panels that surround the test traffic area of the machine. These panels, combined with a separate air conditioning power plant, allow the test traffic area and pavement testing surface to be heated to temperatures of 130°F or cooled to temperatures as low as 30°F. The facility also maintains several load carts in the vehicle fleet, simulating wheel loads of such popular military aircraft as the F-15 Eagle and the C-17 cargo aircraft. Success Stories In Spring 2012, ERDC became the first research institution to evaluate and develop design and construction guidance on the use of warm-mix asphalt (WMA) for airfields. GSL researchers staged the test section construction at the ERDC Pavement Testing Facility in order to test the most uniform pavement sections possible. The evaluations demonstrated the rutting performance of the different WMA technologies compared to conventional hot-mix asphalt (HMA). WMA has many benefits over HMA, including reduced fuel consumption and plant emissions during production. Ultimately, these tests will help determine the suitability of these technologies for airfield pavements. They will also help improve the design and construction guidance of WMA airfield pavements developed by ERDC based on the rutting performance under actual aircraft traffic.

Description
This proposal is responsive to NASA SBIR Topic X10.01, specifically, the need for efficient small- to medium-scale hydrogen liquefaction technologies including domestically produced wet cryogenic turboexpanders. Future NASA missions will require hydrogen liquefaction systems for earth-based, planetary, and lunar surface missions. A critical part of these systems is the cryogenic turboexpanders, which must be designed for high-speed operation and long life, and must be robust against the pressure and momentum excursions and the surface tension effects associated with two-phase flow. On this Phase I/II program, Creare will build and test a cryogenic turboexpander for use in a hydrogen liquefier. The turboexpander will be reliable, compact, lightweight, and efficient and will be able to operate in a two-phase system. We have prior experience in designing and building wet turboexpanders for terrestrial applications as well as small turbomachines for space applications. We plan to leverage this experience to build for NASA a wet turboexpander suitable for operation in both terrestrial and space environments. Our turboexpander will have the innovative option of recovering the expansion work through use of an alternator (i.e., turboalternator) instead of dissipating work using a brake wheel. This approach greatly simplifies controls, improves reliability, and reduces system mass and input power. During the Phase I project, we will optimize the design of the turboexpander for a specific application selected by NASA. On the Phase II project, we will build and test the turboexpander.

Methods to reduce the turbulent viscous skin friction stand out as paramount to increasing the energy efficiency, and therefore the aerodynamic efficiency of supersonic aircraft. Eagle Harbor Technology (EHT) proposes to develop and optimize a MHD plasma injector, which will be used to efficiently reduce the viscous skin friction in supersonic aircraft. EHT has developed similar MHD plasma injection technologies, which have been applied to a number of different fusion energy science, aerospace thruster, and basic research investigations. Here, we aim to computationally investigate and verify the dominant physical mechanisms for MHD plasma drag reduction; develop a proof of concept plasma injector demo, which conforms to necessary power and efficiency requirements for an onboard flight-relevant system; and use insights gained through our computational investigations to optimize the performance of our MHD plasma injector for maximum aerodynamic efficiency. This investigation will focus on flight-relevant Reynolds and magnetic Reynolds numbers at low supersonic (M<~3) speeds. Phase II research will couple the plasma injector to a scale model airframe for detailed in-situ supersonic wind tunnel testing. The phase II research will produce a fully realized working plasma injector prototype that conform to power requirements of an on-board power system.

This data set comprises the Environmental Sensitivity Index (ESI) and Reach Sensitivity Index (RSI) data for Puerto Rico. ESI data characterize estuarine environments and wildlife by their sensitivity to spilled oil. The ESI data include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources. Most rivers and streams can be readily subdivided into clear-cut segments, or reaches (RSI), that have very distinct and uniform characteristics within that reach of the stream. The definition of reach type is usually based on whatever the intended use of the reach classification might be. In this project, stream reaches are defined as those segments where similar spill-response modes and potential ecological and/or socioeconomic impacts from the spill are to be anticipated. However defined, the boundary of the reach is usually marked by an abrupt change in the morphology of the stream, a change commonly, but not always, brought about by an alteration in the stream's gradient. This data set contains polygonal data for human-use resources.
