Global Geopotential Models assessment in Ecuador based on geoid heights and geopotential values

Journal of Geodetic Science, 2023
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

Validation of the Aura Microwave Limb Sounder temperature and geopotential height measurements [PDF]

Journal of Geophysical Research: Atmospheres, 2008
Global satellite observations of temperature and geopotential height (GPH) from the Microwave Limb Sounder (MLS) on the EOS Aura spacecraft are discussed. The precision, resolution, and accuracy of the data produced by the MLS version 2.2 processing algorithms are quantified, and recommendations for data screening are made. Temperature precision is 1 K

Eigen microstates and their evolution of global ozone at different geopotential heights [PDF]

Chaos: An Interdisciplinary Journal of Nonlinear Science, 2021
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.
