A pilot variational coupled reanalysis based on the CESAM climate model

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Variational data assimilation of in‐situ and satellite ocean data and reanalysis atmospheric data into an intermediate complexity Earth system model is possible by adjusting the surface fluxes and internal model parameters. This pilot application requires nearly complete information on the atmospheric state for synchronization.

Calculating of adjusted geoid undulation based on EGM08 and mean sea level for different regions in Iraq

MATEC Web of Conferences, 2018
In last decades Global Navigation Satellite System (GNSS) or as known Global Positioning System (GPS) technique is considered a revolutionary technique in the field of geodetic survey in comparison with traditional techniques (level, theodolite and total

Modulation of North Atlantic atmospheric rivers by the Gulf Stream

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Gulf Stream ocean variability plays a key role in modulating atmospheric river (AR) activity over the North Atlantic during winter and spring at monthly time‐scales. Increased ocean heat transport and mesoscale activity in the Gulf Stream are linked to northward shifts in ARs, while stronger surface heat fluxes drive ARs southward.

Refinement of the Kuwait geoid using the modified Stokes' kernel and Airy-Heiskanen isostatic reduction for GIS and geomatics applications

Egyptian Journal of Remote Sensing and Space Sciences, 2023
Orthometric heights are important for various applications such as GIS, geomatics, engineering, and geoscience. The ellipsoidal heights can be computed by Global Navigation Satellite System (GNSS) as an accurate, rapid, and efficient method for height ...

Mapping Escolar (Lepidocybium flavobrunneum) in Motion: Oceanographic Forces Shaping Its Habitat in the Southwestern South Atlantic, With Insights From Fishers' Perceptions

Fisheries Oceanography, EarlyView.
ABSTRACT Lepidocybium flavobrunneum [Smith, 1843], commonly known as escolar, is a large pelagic species, important for global and local fisheries, particularly in the southwestern South Atlantic Ocean (SWAO), where it constitutes a significant portion of the catch.

New solutions for the geoid potential W0 and the Mean Earth Ellipsoid dimensions

Journal of Geodetic Science, 2013
Earth Gravitational Models (EGMs) describe the Earth’s gravity field including the geoid, except for its zero-degree harmonic, which is a scaling parameter that needs a known geometric distance for its calibration. Today this scale can be provided by the

DASNordicSLR—A Regional Dataset of Sea Level Projections for Northern Europe

Geoscience Data Journal, Volume 13, Issue 2, April 2026.
Relative sea level projections for Northern Europe (DASNordicSLR) combine IPCC‐AR6 projections with vertical land motion data from NKG2016LU. The resulting high‐resolution dataset enables a realistic representation of regional sea level change along coastlines, supporting climate services and coastal risk assessments with spatially detailed insights ...

Signal and error assessment of GOCE-based high resolution gravity field models

Journal of Geodetic Science, 2019
The signal content and error level of recent GOCE-based high resolution gravity field models is assessed by means of signal degree variances and comparisons to independent GNSS-levelling geoid heights. The signal of the spherical harmonic series of these

Combination of Geometric and Orthometric Heights in the Presence of Geoid and Quasi-geoid Models [PDF]

, 2014
A generalization of the well-known relationship between geometric and orthometric heights is presented in this paper. The advantage of our revised formulation is that, instead of the non-determinable true orthometric heights, it employs the (most commonly used in geodetic practice) Helmert orthometric heights.

Recent Observations of Thwaites Glacier, West Antarctica Are Consistent With High Rates of Loss in Next 50 Years

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Thwaites Glacier has experienced accelerating mass loss, with rates increasing over fivefold since the 1990s. We apply transient calibration to two independent ice‐sheet models (STREAMICE and ISSM) using time‐varying velocity and surface elevation data from 2004 to 2017 to project future mass loss through 2067.
