Geoidal Geopotential and World Height System
Studia Geophysica et Geodaetica, 1999The geoidal geopotential value of W 0 = 62 636 856.0 ± 0.5m 2 s −2 , determined from the 1993 –1998 TOPEX/POSEIDON altimeter data, can be used to practically define and realize the World Height System.

Autocorrelation of Northern Hemisphere Geopotential Heights
Monthly Weather Review, 1983Abstract Local autocorrelation statistics for the Northern Hemisphere geopotential height field are presented for different seasons and tropospheric pressure levels. Values are generally much higher than those calculated from time series of outgoing infrared radiation or eddy heat fluxes. The largest one-day lag autocorrelation values are observed over

Deriving orthometric height using global geopotential models (GGMs)
2016 7th IEEE Control and System Graduate Research Colloquium (ICSGRC), 2016The purpose of this paper is to evaluate the orthometric height derived by combination of Global Navigation Satellite System (GNSS) data and global geoid height information over Peninsular Malaysia. The global geoid height information is derived from recent Global Geopotential Models (GGMs); combined and satellite-only solution.

Chronometric Height: a relativistic height definition by generalizing geopotential numbers
2021<p>A height definition in terms of geopotential numbers offers a variety of advantages. Moreover, from the theoretical point of view, such a definition is considered more fundamental.&#160;</p><p>We know, however, that relativistic gravity (here General Relativity) requires to reformulate the basic ...

Secular Variation of Northern Hemisphere 50 kPa Geopotential Height
Journal of Climate, 1988Abstract There is accumulating evidence in the literature that different short-period climate regimes (subclimates) may have characterized the Northern Hemisphere during the past 40 years. We, therefore, investigate the 40-yr record of 50 kPa height (1946–85) and analyze the time series of zonal anomalies stratified by season.

Geopotential Height Errors in NWS Rawinsonde Data at Denver
Bulletin of the American Meteorological Society, 1988A recent examination of Denver National Weather Service radiosonde data has revealed an error in the procedure used to establish the surface baseline pressure for Denver soundings obtained between 14 April 1983 and 2 March 1988. As a result of this error the baroswitch was improperly set on each sounding, resulting in geopotential heights that average ...

On the Interpretation of Geopotential Height Tendency Equations
Monthly Weather Review, 1993Abstract The conceptual model for height tendency presented by Hirschberg and Fritsch directly links upper-level virtual temperature tendency with low-level height tendency, overlooking the essential dynamics of mass divergence. An analysis of the complete height tendency equation shows that upper-level virtual temperature change car only indirectly ...

Survey Review, 1963
Abstract Some geodetic methods are geometrical, some are physical, and others have something of both these qualities. In recent years there has been a tendency to mark this distinction more clearly, to the benefit of geodetic science in general.

Chinese Journal of Geophysics, 2007
AbstractGeopotential height data at 500hPa level in recent 50 years is used to investigate the evolutive laws of Antarctic, Equatorial and Arctic geopotential heights, zonal wind, and the correlation between one and another. Results show that Antarctic (Equatorial) geopotential height descends (ascends) evidently.

Bispectral analysis of geopotential‐height anomalies for synoptic‐intraseasonal time‐scales
Quarterly Journal of the Royal Meteorological Society, 2001AbstractSpectral decomposition of the third moment of geopotential‐height fluctuations, bispectral analysis, is considered as a convenient and straightforward method of studying the nonlinear three‐wave interactions between spectral constituencies of anomalies.
