An EOF-Based Global Plasmaspheric Electron Content Model and Its Potential Role in Vertical-Slant TEC Conversion

Remote Sensing
Topside total electron content (TEC) data measured by COSMIC/FORMAT-3 during 2008 and 2016 were used to analyze and model the global plasmaspheric electron content (PEC) above 800 km with the help of the empirical orthogonal function (EOF) analysis ...

Redefining the North Atlantic Oscillation index generation using autoencoder neural network

Machine Learning: Science and Technology
Understanding the spatial patterns of the North Atlantic Oscillation (NAO) is vital for climate science. For this reason, empirical orthogonal function (EOF) analysis is commonly applied to sea-level pressure (SLP) anomaly data in the North Atlantic ...

EOF-UViT Model: A New Deep Learning Model to Reconstruct the Three-Dimensional Salinity Based on Multi-Source Remote Sensing Data

Remote Sensing
Accurate three-dimensional (3D) salinity fields are crucial for diagnosing freshwater transport and upper-to-intermediate ocean dynamics, yet subsurface salinity observations remain uneven in space and time, especially away from primary observing ...

A Multiscale GR-EOF Approach Reveals Climate Mode Biases in Sea Level Rise Estimates

Applied Ocean Research
Satellite altimetry has revealed a persistent non-uniform global sea level rise over the past three decades, but trend estimates remain sensitive to internal climate variability on interannual to decadal timescales. Here, we develop an improved global-to-

Detection of Dominant Rainfall Patterns in Indonesian Regions Using Empirical Orthogonal Function (EOF) and Its Relation with ENSO and IOD Events

Science and Technology Indonesia
Several studies indicate that Indonesia’s position on the equator, where winds from the northern and southern hemispheres converge, leads to year-round rainfall in Indonesia. Previous studies have also shown the presence of monsoon winds over Indonesia, which causes rain in Indonesia to follow the Asian and Australian monsoon wind patterns.
