Transportation Satellite Accounts Table

The Transportation Satellite Accounts (TSAs) provide a means for measuring the contribution of transportation services to the national economy. Prior to the TSAs, the magnitude of transportation services had long been underestimated, as most national measures counted only the value of for-hire services. Measurement of services provided only by for-hire firms misses the sizable contribution of transportation services that take place within nontransportation industries, termed as in-house transportation.

To more accurately measure transportation services, the Bureau of Transportation Statistics (BTS) of the U.S. Department of Transportation and the Bureau of Economic Analysis (BEA) of the U.S. Department of Commerce, jointly developed the Transportation Satellite Accounts (TSAs). The TSAs, as a supplement to the U.S. Input-Output (I-O) Accounts, measure the contribution of both for-hire and in-house transportation. The TSAs include all seven of the for-hire transportation industries reported in the U.S. I-O accounts and four in-house transportation modes.

National Environmental Policy Act

The National Environmental Policy Act (NEPA) was the first major environmental law in the United States and established national environmental policies for the country.  NEPA mandates federal agencies to consider the impacts of their activities-including the issuance of federal permits, Federal funding, and other federal agency actions-on the environment, and to ensure that information about these environmental impacts is available to the public before final decisions are made.  The Council on Environmental Quality (CEQ) promulgates regulations that require agencies to create their own NEPA implementing procedures.  These procedures must meet the CEQ standard while reflecting each agency's unique mandate and mission.  Consequently, NEPA procedures vary from agency to agency.

Automated Discovery of Flight Track Anomalies

As new technologies are developed to handle the complexities of the Next Generation Air Transportation System (NextGen), it is increasingly important to address both current and future safety concerns along with the operational, environmental, and efficiency issues within the National Airspace System (NAS). In recent years, the Federal Aviation Administration’s (FAA) safety offices have been researching ways to utilize the many safety databases maintained by the FAA, such as those involving flight recorders, radar tracks, weather, and many other high-volume sensors, in order to monitor this unique and complex system. Although a number of current technologies do monitor the frequency of known safety risks in the NAS, very few methods currently exist that are capable of analyzing large data repositories with the purpose of discovering new and previously unmonitored safety risks. While monitoring the frequency of known events in the NAS enables mitigation of already identified problems, a more proactive approach of finding unidentified issues still needs to be addressed. This is especially important in the proactive identification of new, emergent safety issues that may result from the planned introduction of advanced NextGen air traffic management technologies and procedures. Development of an automated tool that continuously evaluates the NAS to discover both events exhibiting flight characteristics indicative of safety-related concerns as well as operational anomalies will heighten the awareness of such situations in the aviation community and serve to increase the overall safety of the NAS. This paper discusses the extension of previous anomaly detection work to identify operationally significant flights within the highly complex airspace encompassing the New York area of operations, focusing on the major airports of Newark International (EWR), LaGuardia International (LGA), and John F. Kennedy International (JFK). In addition, flight traffic in the vicinity of Denver International (DEN) airport/airspace is also investigated to evaluate the impact on operations due to variances in seasonal weather and airport elevation. From our previous research, subject matter experts determined that some of the identified anomalies were significant, but could not reach conclusive findings without additional supportive data. To advance this research further, causal examination using domain experts is continued along with the integration of air traffic control (ATC) voice data to shed much needed insight into resolving which flight characteristic(s) may be impacting an aircraft's unusual profile. Once a flight characteristic is identified, it could be included in a list of potential safety precursors. This paper also describes a process that has been developed and implemented to automatically identify and produce daily reports on flights of interest from the previous day.

IRIS/Nimbus-4 Level 1 Radiance Data V001 (IRISN4RAD) at GES DISC

The Nimbus-4 Infrared Interferometer Spectrometer (IRIS) Level 1 Radiance Data contain thermal emissions of the Earth's atmosphere at wave numbers between 400 and 1600 cm**-1, with a nominal resolution of 2.8 cm**-1.  The data also contain documentation information, reference calibration, average instrument temperatures, and a summary for each orbital pass.  The data, originally written on IBM 360 machines, were recovered from 9-track magnetic tapes.  The data are archived in their original IBM 32-bit word binary record format, and each file contains an entire day of measurements.  The product contains data from April 9, 1970 (day of year 99) through Jan 31, 1971 (day of year 31).

The IRIS instrument was designed to provide information on the vertical structure of the atmosphere and on the emissive properties of the earth's surface by measuring the surface and atmospheric radiation in the 6.25 to 25 micrometer range using a modified Michelson interferometer.  IRIS viewed along the satellite track direction with a spatial resolution of 94 km at nadir.  A Fourier transform was applied to the interferograms to produce thermal emmision spectra of the Earth which could be used to derive vertical profiles of temperature, water vapor, and ozone, as well as other parameters of meteorological interest.  The Infrared Interferometer Spectrometer (IRIS) experiment on Nimbus-4 is a follow on experiment to the Nimbus-3 IRIS experiment.  The IRIS Principal Investigator was Dr. Rudolf A. Hanel.

These data were previously archived at NASA NSSDC under the entry ID ESAD-00093 (originally 70-025A-03A).

Exploration of the Transition Region-Corona Interface With the Multi-Order Solar EUV Spectrograph Project

&lt;p&gt;
	We propose to observe the solar upper transition region and lower corona in Ne VII 46.5 nm with the Multi-Order Solar EUV Spectrograph (MOSES) rocket payload. The solar plasma in this temperature range, about 500,000 K, has not been imaged at rapid cadence since Skylab (Feldman, 1987). The unique observational capabilities of MOSES, demonstrated already in He II 30.4 nm, enable simultaneous imaging and measurement of line widths and doppler shifts over a large (20&amp;rsquo; x 10&amp;rsquo;) field of view, with typical active region exposure times of 10 s. These observations will reveal the 3D dynamics of outflows and reconnection events in active regions, quiet Sun, and coronal holes. The primary objectives of this one-year proposal are (1) instrument calibration, (2) launch of the rocket in summer of 2012, and (3) data analysis, including exploration of new techniques to recover more spectral information from the MOSES data. Prior NASA funding has enabled data analysis and publication of results from the first flight, upgrades to the payload, and increased reliability of our ground support equipment. Procurement of optics to observe the Ne VII 46.5 nm line is in process. With the help of additional funding from Montana Space Grant Consortium, we have also developed an EUV calibration facility optimized for testing the MOSES payload.&lt;/p&gt;

AIRS/Aqua L1B Near Real Time (NRT) Infrared (IR) quality assurance subset V005 (AIRIBQAP_NRT) at GES DISC

The AIRS Level 1B Near Real Time (NRT) product (AIRIBQAP_NRT_005) differs from the routine product (AIRIBQAP_005) in 2 ways to meet the three hour latency requirements of the Land Atmosphere NRT Capability Earth Observing System (LANCE): (1) The NRT granules are produced without previous or subsequent granules if those granules are not available within 5 minutes, (2) the predictive ephemeris/attitude data are used rather than the definitive ephemeris/attitude. The consequences of these differences are described in the AIRS Near Real Time (NRT) data products document. The Atmospheric Infrared Sounder (AIRS) is a facility instrument aboard the second Earth Observing System (EOS) polar-orbiting platform, EOS Aqua. In combination with the Advanced Microwave Sounding Unit (AMSU) and the Humidity Sounder for Brazil Humidity Sounder for Brazil (HSB), AIRS constitutes an innovative atmospheric sounding group of visible, infrared, and microwave sensors. AIRS data will be generated continuously. Global coverage will be obtained twice daily (day and night) on a 1:30pm sun synchronous orbit from a 705-km altitude. The AIRS IR Level 1B QA Subset contains Quality Assurance (QA) parameters that a user of may use to filter AIRS IR Level 1B radiance data to create a subset of analysis. QA parameters indicate quality of granule-per-channel, scan-per-channel, field of view, and channel and should be accessed before any data of analysis. It also contains "glintlat", "glintlon", and "sun_glint_distant" that users can use to check for possibility of solar glint contamination.

GPM Ground Validation Daily Precipitation OLYMPEX V1

The GPM Ground Validation Daily Precipitation Olympic Mountain Experiment (OLYMPEX) dataset consists of a single netCDF-4 data file containing estimates of daily precipitation, both rainfall and snowfall amounts, on a 1/32 degree spatial resolution grid covering the extent of the OLYMPEX field campaign region in the Olympic Mountains of the state of Washington. This data product was created for the GPM Ground Validation OLYMPEX field campaign. These VIC precipitation estimates are based on NOAA WSR-88D radar and rain gauge data incorporated in NOAA’s National Severe Storms Laboratory (NSSL) local gauge bias-corrected radar quantitative precipitation estimation (QPE) model (product Q3GC) and the Mountain Mapper QPE model (product Q3MM). The VIC hydrology model was used to invert the snow water equivalent (SWE) values to derive precipitation through adjustment of the precipitation-weighting factor on a grid cell by grid cell basis. The VIC precipitation data are available from October 1, 2015 through April 30, 2016.
