Summary
Description
As air-breathing combustion applications advance, increased use of fuel for cooling, combined with cycle advancements, leads to a situation where the fuel can become superheated. While this can lead to potential benefit in terms of the eventual fuel injection process, with enhanced atomization and evaporation, it creates a significant challenge relative to any computational design tools that might be used in these systems. Dealing with the superheat behavior in the injection of a liquid fuel requires substantially more physical phenomena to be accounted for compared to a subcooled system. As a result, detailed data and models for this behavior as encountered in practical fuels are needed in order to validate and evolve the models needed. In the work proposed, emphasis will be given to the injection of a plain liquid jet under superheated conditions. In Phase I the behavior of the liquid internal to the injector will be addressed, with both models and experiments carried out. The models evolved will be incorporated into an existing simulation environment developed by ERC for atomization of liquid jets. In addition, data will be available for CFD validation.

Summary
Description
Bathythermograph data were collected from the BIBB within a 1-mile radius of Ocean Weather Station B (5630N 05100W) and in transit. Data were collected by the United States Coast Guard from 25 September 1973 to 07 October 1973. The platform was equipped and staffed to observe weather and sea conditions. Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/bt.html. The UBT file format is used for temperature-depth profile data obtained using expendable bathythermograph (XBT) instrument. Standard XBTs can obtain profiles at depths of about 450 or 760 m. With special instruments, measurements can be obtained to 1830 m. Cruise information, position, date, and time are reported for each observation. The data record comprises pairs of temperature-depth values. Unlike the MBT data file, in which temperature values are recorded at uniform 5m intervals, the XBT Data File contains temperature values at non-uniform depths. These depths are at a minimum number of points ("inflection points") required to record the temperature curve to an acceptable degree of accuracy. On output, however, the user may request temperature values either at inflection points or interpolated to uniform depth increments.

The danger from fire aboard spacecraft is immediate with only moments for detection and suppression. Spacecraft are unique high-value systems where the cost of failure is measured in lives and dollars. Space crews have little or no chance to escape vessels on fire. It is imperative to detect the onset of combustion in microgravity at the earliest possible moment. Present fire detectors onboard spacecraft are inadequate due to sensitivity, time response, or both. Smoke detectors are insufficient for detecting the early stages of combustion, sensors are needed to detect the products of combustion directly. These sensors must meet stringent size, weight and power requirements. Vista Photonics proposes to develop rugged, compact fire detection instrumentation capable of selectively and simultaneously measuring the combustion species HCN, acetylene, carbon dioxide and carbon monoxide at parts-per-million (ppm) or better sensitivities in a 1 Hz bandwidth. The enabling technology for meeting NASA's stringent mission requirements is a new rugged, compact, and lightweight optical path length enhancement cell that recovers the theoretical sensitivity of proven high-performance optical absorption detection techniques.

Environmental Sensitivity Index (ESI) maps are an integral component in oil-spill contingency planning and assessment. They serve as a source of information in the event of an oil spill incident.ESI maps contain three types of information: shoreline habitats (classified according to their sensitivity to oiling), sensitive biological resources, and human-use resources. Most often, this information is plotted on 7.5 minute USGS quadrangles, although in the Alaska ESI maps, USGS topographic maps at scales of 1:63,360 and 1:250,000 are used, and in other ESI maps, NOAA charts have been used as the base map. Collections of these maps, grouped by state or a logical geographic area, are published as ESI atlases. Digital data have been published for most of the U.S. shoreline, including Alaska, Hawaii, and Puerto Rico.

Summary
Description
Current meter components data were collected from FIXED PLATFORMS in the Gulf of Mexico from 17 July 1980 to 01 February 1981. Data were collected by Texas A&M University (TAMU). Data were processed by NODC to the NODC standard F015 Current Meter Components format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/f015.html. The F015 format contains time series measurements of ocean currents. These data are obtained from current meter moorings and represent the Eulerian method of current measurement, i.e., the meters are deployed at a fixed point and measure flow past a sensor. Position, bottom depth, sensor depth and meter characteristics are reported for each station. The data record includes values of east-west (u) and north-south (v) current vector components at specified date and time. Current direction is defined as the direction toward which the water is flowing with positive directions east and north. Data values may be subject to averaging or filtering and are typically reported at 10 - 15 minute time intervals. Water temperature, pressure and conductivity or salinity may also be reported. A text record is available for optional comments.

This dataset is part of the collection of Special Sensor Microwave/Imager (SSM/I) and Special Sensor Microwave Imager Sounder (SSMIS) data products produced as part of NASA's MEaSUREs Program. Remote Sensing Systems generates SSM/I and SSMIS binary data products using a unified, physically based algorithm to simultaneously retrieve ocean wind speed (at 10 meters), water vapor, cloud water, and rain rate. The SSMIS data have been carefully intercalibrated on the brightness temperature level with the previous SSM/I and therefore extend this important time series of ocean winds, vapor, cloud and rain values. This algorithm is a product of 20 years of refinements, improvements, and verifications. The Global Hydrology Resource Center has reformatted the binary data into a netCDF data product for each temporal group for each satellite. The netCDF SSMI/SSMIS collection will be available for F8, F10, F11, F13, F14, F15, F16, F17 for each temporal aggregation: daily, 3-day, weekly and monthly.

Summary
Description
The Tropical Rainfall Measuring Mission (TRMM) is a joint U.S.-Japan satellite mission to monitor tropical and subtropical precipitation and to estimate its associated latent heating. TRMM was successfully launched on November 27, at 4:27 PM (EST) from the Tanegashima Space Center in Japan. The Visible and Infrared Scanner (VIRS) is a five-channel visible/infrared radiometer, which builds on the heritage of the Advanced Very High Resolution Radiometer (AVHRR) instrument flown aboard the NOAA series of Polar-Orbiting Operational Environmental Satellites (POES). The VIRS detects radiation at 1 visible, 2 near infrared and 2 thermal infrared wavelengths, allowing determination of cloud coverage, cloud top height and temperature, and precipitation indices. The central wavelengths for the VIRS channels are 0.63, 1.60, 3.75, 10.8, and 12.0 microns. All channels are in operation during the daytime, but only channels 3, 4 and 5 operate during the nighttime. The Level 1A product file (1A01) is a concatenation of the Level 0 data with a header record and, as such, is reversible to Level 0. The header record contains information pertaining to orbit times, orbit number, times of the first scan, and number of scans, among other things. The Level 0 data contain the actual channel data expressed as "sensor counts". A Level 1A file contains data for a single orbit and has a file size of about 31 MB (uncompressed). There are 16 files of VIRS 1A01 data produced per day. Spatial coverage is between 38 degrees North and 38 degrees South owing to the 35 degree inclination of the TRMM satellite. This orbit provides extensive coverage in the tropics and allows each location to be covered at a different local time each day, enabling the analysis of the diurnal cycle of precipitation.
