Category Scope
46 Geophysics Includes earth structure and dynamics, aeronomy; upper and lower atmosphere studies; ionospheric and magnetospheric physics; and geomagnetism. For related information see 47 Meteorology and Climatology; and 93 Space Radiation. Definition Geophysics – The physics of the Earth and its environment, i.e., its solid earth, air, waters and (by extension) space. NASA Thesaurus, Washington, DC: National Aeronautics and Space Administration. Dictionary of Technical Terms for Aerospace Use. Wm. H. Allen, ed., 1965. NASA SP-7. NASA Interest Exhaustive Interest : Physics of the Earth, including its atmosphere and its hydrosphere, as revealed by aircraft, satellite, and manned spacecraft observations; observation of natural phenomena; upper atmosphere and ionosphere; geomagnetism and Earth gravitational field; paleontology related to development of life; geological investigations having potential relevance to ground truth for remote sensing or Earth evolution and structure. Selective Interest : Geology of direct interest to aerospace activities. Negative Interest : Surface surveys; surface or seismic prospecting; assaying processes or records. | |
