Argon-ion contamination of the plasmasphere

Description: This paper applies present observational and analytic knowledge on effects of plasma beam interaction wth the magnetosphere to the plasmasphere contamination problem of the argon ion engine exhaust expected to be deposited in the magnetosphere during the construction phase of the Satellite Power System. Effects of plasmasphere, ionosphere, and radiation belt modifications are discussed.

Superpressure Stratospheric Vehicle

Description: Our need for wide-band global communications, earth imaging and sensing, atmospheric measurements and military reconnaissance is extensive, but growing dependence on space-based systems raises concerns about vulnerability. Military commanders require space assets that are more accessible and under local control. As a result, a robust and low cost access to space-like capability has become a national priority. Free floating buoyant vehicles in the middle stratosphere can provide the kind of cost… more

Environmental Implementation Plan

Description: The purpose of the Environmental Implementation Plan (EIP) is to show the current and future (five years) environmental plans from individual site organizations and divisions, as well as site environmental programs and initiatives which are designed to protect the environment and meet or exceed changing environmental/regulatory requirements. Communicating with site organizations, departments, and committees is essential in making the site's environmental-planning process work. The EIP gives the… more

A note on the behavior of stack gases

Description: The ability of the atmosphere to disperse and diffuse smoke and gases varies widely with weather conditions. The rate of diffusion is governed mainly by the degree of atmospheric turbulence present. The latter is in itself an extremely complex air motion which acts as the mixing agent in diffusion. This turbulence, which is so fundamental in the diffusion process, depends on such quantities as wind speed, rate of change of wind speed or wind direction with height, and rate of change of air temp… more

A Year of Radiation Measurements at the North Slope of Alaska Second Quarter 2009 ARM and Climate Change Prediction Program Metric Report

Description: In 2009, the Atmospheric Radiation Measurement (ARM) Program and the Climate Change Prediction Program (CCPP) have been asked to produce joint science metrics. For CCPP, the second quarter metrics are reported in Evaluation of Simulated Precipitation in CCSM3: Annual Cycle Performance Metrics at Watershed Scales. For ARM, the metrics will produce and make available new continuous time series of radiative fluxes based on one year of observations from Barrow, Alaska, during the International Pola… more

Atmospheric Radiation Measurement Program Climate Research Facility Operations Quarterly Report - October 1 - December 31, 2008

Description: Description. Individual raw data streams from instrumentation at the Atmospheric Radiation Measurement (ARM) Program Climate Research Facility (ACRF) fixed and mobile sites are collected and sent to the Data Management Facility (DMF) at Pacific Northwest National Laboratory (PNNL) for processing in near real-time. Raw and processed data are then sent daily to the ACRF Archive, where they are made available to users. For each instrument, we calculate the ratio of the actual number of data record… more

Monitoring the response of the upper troposphere/lower stratosphere to a greenhouse gas scenario

Description: During the past two years a system has been under development to contribute to this monitoring process by making measurement of the downwelling infrared radiance field at moderate spectral resolution. Sensitivity of the measurements to the presence of cirrus cloudiness, and effective particle size in cirrus clouds has been demonstrated. Sensitivity of the measurements to concentration of C0[sub 2] and to the gross temperature structure of a 2CO[sub 2] atmosphere have been modeled, and measureme… more

Sources of Ozone and Sulfate in Northeastern United States. Annual Progress Report. [Determination of Anthropogenic Sources from Measurements at Whiteface Mountain, New York]

Description: Measurements of daily concentrations of /sup 7/Be, /sup 32/P, and ozone at Whiteface Mountain, New York are reported for June, July, and August of 1977 and 1978. Episodes of high daily ozone are observed to coincide with peak /sup 7/Be and /sup 32/P concentrations. Since these radionuclides and ozone are produced in the stratosphere, their simultaneous increase is taken to indicate the arrival of stratospheric air. However, ozone is also produced at ground level by photochemical reactions. Ther… more

Damage from the impacts of small asteroids

Description: The fragmentation of a small asteroid in the atmosphere greatly increases its aerodynamic drag and rate of energy dissipation. The differential atmospheric pressure across it disperses its fragments at a velocity that increases with atmospheric density and impact velocity and decreases with asteroid density. Extending our previous work, we use a spherical atmosphere and a fitted curve to its density profile to find the damage done by an asteroid entering the atmosphere at various zenith angles.… more

Integrated ground-based and remotely sensed data to support global studies of environmental change

Description: Data centers routinely archive and distribute large databases of high quality and with rigorous documentation but, to meet the needs of global studies effectively and efficiently, data centers must go beyond these traditional roles. Global studies of environmental change require integrated databases of multiple data types that are accurately coordinated in terms of spatial, temporal and thematic properties. Such datasets must be designed and developed jointly by scientific researchers, computer… more

Measurement of emission fluxes from Technical Area 54, Area G and L. Final report

Description: The emission flux (mass/time-area) of tritiated water from TA-54 was measured to support the characterization of radioactive air emissions from waste sites for the Radioactive Air Emissions Management (RAEM) program and for the Area G Performance Assessment. Measurements were made at over 180 locations during the summers of 1993 and 1994, including randomly selected locations across Area G, three suspected areas of contamination at Area G, and the property surrounding TA-54. The emission fluxes… more
