ICESat-2 for Coastal MSS Determination—Evaluation in the Norwegian Coastal Zone
Remote Sensing, 2023 Radar satellite altimeters enable the determination of the mean sea surface to centimeter accuracy, which can be degraded in coastal areas because of the lack of valid altimetry observations due to land contamination and the altimeter footprint size.

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract Dendritic valley networks on Mars have been cited as evidence for a warm and wet Noachian Mars, permitting rainfall precipitation and surface runoff. However, the climatic conditions required to sustain rainfall on early Mars remain debated.

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Gravity Recovery and Climate Experiment (GRACE) observation data processed by various institutions yields somewhat different spherical harmonic solutions, which are further used to derive terrestrial water storage (TWS) changes. Combining TWS solutions from different institutions helps to refine the effective signal while removing noise.
