Investigation of a geodesy coexperiment to the Gravity Probe B relativity gyroscope program [PDF]
Geodesy is the science of measuring the gravitational field of and positions on the Earth. Estimation of the gravitational field via gravitation gradiometry, the measurement of variations in the direction and magnitude of gravitation with respect to ...

The Impact of Adaptive High‐Latitude Coordinates
Geophysical Research Letters, Volume 52, Issue 16, 28 August 2025.Abstract The high‐latitude ionosphere can be divided into three regions dominated by different types of coupling and characterized by distinctive behaviors. These are the polar cap, the auroral region, and the sub‐auroral region. Their locations are highly variable, changing in extent in response to driving conditions in the solar wind and within the ...

Impact of Raman Scattering on SIF Retrievals From Hyperspectral Satellite Observations
Geophysical Research Letters, Volume 52, Issue 15, 16 August 2025.Abstract Solar‐induced chlorophyll fluorescence (SIF) retrieved from spaceborne measurements is widely used as an indicator of vegetation activity. However, this weak emission can be confused with the inelastic scattering component of sunlight that lacks distinctive Fraunhofer lines.

Conservative evaluation of the uncertainty in the LAGEOS-LAGEOS II Lense-Thirring test
, 2009 We deal with the test of the general relativistic gravitomagnetic Lense-Thirring effect currently ongoing in the Earth's gravitational field with the combined nodes \Omega of the laser-ranged geodetic satellites LAGEOS and LAGEOS II.

Geophysical Research Letters, Volume 52, Issue 15, 16 August 2025.Abstract The Moon encountered an extreme space weather event (NOAA G5 class) on 10 May 2024, caused by a series of coronal mass ejections (CMEs). Chandra's Atmospheric Composition Explorer‐2 (CHACE‐2), a neutral gas mass spectrometer on board Chandrayaan‐2 orbiter, made in situ observations of the lunar exosphere during this period.

The Uganda Gravimetric Geoid Model 2014 Computed by The KTH Method
Journal of Geodetic Science, 2015 For many developing countries such as Uganda, precise gravimetric geoid determination is hindered by the low quantity and quality of the terrestrial gravity data.

Gravity field, geoid and ocean surface by space techniques [PDF]
Knowledge of the earth's gravity field continued to increase during the last four years. Altimetry data from the GEOS-3 satellite has provided the geoid over most of the ocean to an accuracy of about one meter.
