The plasma Environment of Mars
(Kluwer Academic Publishers; Springer Science+Business Media, 2004-03)
Ground-based measurements of O1D and the H2O production rate from comets
(Elsevier, 1989)
Ground-based high spectral resolution measurements of Comet Halley in the 6300.3 A spectral region establish this technique as a powerful and low cost method for determining cometary H2O production rates. A model on the ...
Effect of ambient humidity on dichotomous sampler coarse/fine ratios
(Elsevier, 1988)
Atmospheric aerosols were measured in August 1983 on Allegheny Mountain and Laurel Hill in southwestern Pennsylvania. Ambient humidity was observed to influence the coarse to fine particle ratios as determined by dichotomous ...
Cassini Radio Science
(Kluwer Academic Publishers; Springer Science+Business Media, 2004-11)
Cassini radio science investigations will be conducted both during the cruise (gravitational wave and conjunction experiments) and the Saturnian tour of the mission (atmospheric and ionospheric occultations, ring occultations, ...
On the potential of regional-scale emissions zoning as an air quality management tool for the grand canyon
(Elsevier, 1994-03)
Air arriving at the Grand Canyon of the Colorado River during 1988-1989 is attributed to one of four geographic quadrants--NE, SE, SW, NW--on the basis of routinely calculated back-trajectories. Most of the haze observed ...
Measurement of minor species (H2, Cl, O3, NO) in the earth's atmosphere by the occultation technique
(Elsevier, 1981)
The stellar occultation technique is a clean and powerful means of detecting and quantifying minor gases in the earth's atmosphere. The results obtained are totally insensitive to knowledge of the absolute flux of the star, ...
Galileo Probe Mass Spectrometer experiment
(Kluwer Academic Publishers; Springer Science+Business Media, 1992-05)
The Galileo Probe Mass Spectrometer (GPMS) is a Probe instrument designed to measure the chemical and isotopic composition including vertical variations of the constituents in the atmosphere of Jupiter. The measurement ...
Abundances of Deuterium and Helium-3 in the Protosolar Cloud
(Kluwer Academic Publishers; Springer Science+Business Media, 1998-04)
The mass spectrometric determinations of the isotopic composition of helium in the solar wind obtained from (1) the Apollo Solar Wind Composition (SWC) experiment, (2) the Ion Composition Instrument (ICI) on the International ...
The Solar Origin of Corotating Interaction Regions and Their Formation in the Inner Heliosphere
(Kluwer Academic Publishers; Springer Science+Business Media, 1999-03)
Corotating Interaction Regions (CIRs) form as a consequence of the compression of the solar wind at the interface between fast speed streams and slow streams. Dynamic interaction of solar wind streams is a general feature ...
Galileo Probe Measurements of D/H and 3He/4He in Jupiter's Atmosphere
(Kluwer Academic Publishers; Springer Science+Business Media, 1998-04)
The Galileo Probe Mass Spectrometer measurements in the atmosphere of Jupiter give D/H = (2.6 ± 0.7) × 10-5 3He/4He = (1.66 ± 0.05) × 10-4
