Global Geopotential Models assessment in Ecuador based on geoid heights and geopotential values
Since the 1960s, the analysis of disturbed satellite orbits to infer Earth’s gravity field functionals has been an important element in determining the Earth’s gravitational field. The long wavelengths of the gravitational field are recovered through the

Asymmetric Geopotential Height Fluctuations from Symmetric Winds [PDF]
Abstract As a characterization of the variability of observed geopotential height fluctuations, their probability density function (PDF) and its skewness are studied in the global domain for winter and summer. The PDF of the geopotential, Φ, is skewed toward low anomalies at midiatitudes and toward high anomalies in polar and tropical regions.

Chronometric Height: a relativistic height definition by generalizing geopotential numbers
<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 ...

Rising geopotential height under global warming
Abstract Geopotential height (H) is a widely used metric for atmospheric circulation. H has been reported to be rising under global warming, but the amplitude and mechanism of this rise are not clear. Based on reanalysis datasets and climate models participating in CMIP6, this study quantitatively evaluates the sensitivity of H to global mean ...

Estimation of Geopotential Value W0 for the Geoid and Local Vertical Datum Parameters
Unification of the global vertical datum has been a key problem to be solved for geodesy over a long period, and the main challenge for unifying the global vertical datum system is to determine the geopotential value W0 of the geoid and to calculate the ...

CORRELATIONS BETWEEN AREAL PRECIPITATION AND 850-MILLIBAR GEOPOTENTIAL HEIGHT [PDF]
Abstract Geopotential heights of the 850-mb surface at 499 grid points over one-half of the Northern Hemisphere, extending from 10°E westward to 170°W, were correlated with daily precipitation observations over California and an area in the Eastern United States on 401 January and February days. Correlations as high as 0.69 were obtained between 850-mb

Linear Trends in Northern Hemisphere Tropospheric Geopotential Height and Temperature Patterns [PDF]
Gridded National Meteorological Center data for 500 mb geopotential height and 300-500 mb and 500-700 mb thickness for the period 1951-1978 are subjected to linear trend analyses. The analyses are carried out for each calendar month. Significant geographical and seasonal distributions of cooling and warming patterns are found.

Eigen microstates and their evolution of global ozone at different geopotential heights [PDF]
Studies on stratospheric ozone have attracted much attention due to its serious impacts on climate changes and its important role as a tracer of Earth’s global circulation. Tropospheric ozone as a main atmospheric pollutant damages human health as well as the growth of vegetation.
