Sea state bias (SSB) is a crucial error of satellite radar altimetry over the ocean surface. For operational nonparametric SSB (NPSSB) models, such as two-dimensional (2D) or three-dimensional (3D) NPSSB, the solution process becomes increasingly com

Inversion of the underwater temperature anomaly of mesoscale eddies from sea surface remote sensing data plays an important role in understanding the three-dimensional structure of eddies. In this article, a neural network structure, named the eddy t

Global climate change can significantly affect lake systems. However, our understanding of extreme events in lake water levels on a global scale remains relatively limited. In this study, we conducted a quantitative analysis of extreme water level ev
