An improvement to short term variability in Global Mean Sea Level reconstruction [PDF]

Ocean Science
We hypothesise that there is an overestimation of Global Mean Sea Level (GMSL) variability from GMSL empirical orthogonal function (EOF) reconstructions due to differences between the tide gauge observations and their corresponding altimetry data.

Millennial‐Scale Climate States Alter Atlantic Multidecadal Variability Mechanisms in a Climate Model

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The Atlantic Multidecadal Variability (AMV) influences North Atlantic sea surface temperatures and regional climate phenomena such as European droughts and hurricane activity. Its mechanisms remain complex due to long timescales and ocean‐atmosphere interactions.

Contribution of the Pacific Decadal Oscillation to Global Mean Sea Level Trends: Revisited

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Three decades of satellite altimeter observations reveal a continued rise in global mean sea level (GMSL), with the rate of rise reflecting the combined effects of decadal variability and long‐term warming. By decomposing 30‐year running trends of reconstructed sea level over 1950–2019, we quantify the contribution associated with the Pacific ...

Assesment and comparison of modis aod and ae product over Ilorin Aeronet station using the statistical analysis of empirical orthogonal function (EOF)

, 2019
In this Paper, Empirical Orthogonal Function (EOF) was used to assess the MODIS C006 LV2 aerosol AOD and AE products, and compared the data with AERONET AOD and AE observations.

ENSO's Imprint on the Southern Ocean: Wind Waves Drive Surface Cross‐Frontal Flow

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Tropical teleconnection associated with El Niño–Southern Oscillation (ENSO) is widely recognized for regulating multiple physical processes in the Southern Ocean. However, despite its influence on Southern Ocean wind patterns, the response of surface flow has received little attention.

Wave-turbulence separation at a tidal energy site with empirical orthogonal function analysis [PDF]

, 2021
Acoustic Doppler current profilers (ADCPs) are the standard tool for measuring tidal currents at tidal stream energy sites; they are used to estimate several parameters, including turbulent kinetic energy (TKE).

Multidecadal Changes in Atmospheric Dryness Over East Asia Dominated by Internal Climate Variability

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Summer near‐surface vapor pressure deficit (VPD), a key measure of atmospheric dryness, has increased markedly across East Asia since 1980, yet the relative roles of external forcing and internal variability (IV) in its multidecadal changes remain unclear.

A Shift of Multidecadal Trend in Coastal Upwelling Off Southern Vietnam in the South China Sea Around 1999

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract To explore multidecadal trends of the Vietnamese Southern Coastal Upwelling (SCU), we employed an SCU index (Southern Coastal Upwelling index [SCUI]), defined as the difference between basin‐wide SST (Tref ${T}_{\mathrm{r}\mathrm{e}\mathrm{f}}$) and local minimum SST (Tmin ${T}_{\min }$).

Modes of high‐latitude electric field variability derived from DE‐2 measurements: Empirical Orthogonal Function (EOF) analysis [PDF]

Geophysical Research Letters, 2002
In this study we characterize dominant modes of high‐latitude electric field variability as a set of two‐dimensional empirical orthogonal functions (EOFs), based on a sequential non‐linear regression analysis of the electric field derived from plasma drift measurements during the Dynamics Explorer‐2 (DE‐2) satellite mission (1981–1983).

Spatial and temporal variation of total electron content as revealed by principal component analysis [PDF]

Annales Geophysicae, 2016
Eleven years of global total electron content (TEC) data derived from the assimilated thermosphere–ionosphere electrodynamics general circulation model are analyzed using empirical orthogonal function (EOF) decomposition and the corresponding ...
