Summary: After successfully launching and commissioning Metop-C in November 2018, all three satellites of the EUMETSAT Polar System (EPS) are now in orbit and operational, providing support for operational meteorology and climate monitoring. The system, developed in collaboration with partners, has demonstrated enhanced reliability and generated results beyond expectations over a 20+ year period. Multiple satellites in orbit have enabled the production of additional products with increased impact, such as atmospheric motion vector products and improved atmospheric soundings.

Summary: This experiment aimed to establish high-quality standards for rotation and strain measurements in seismology. Through a comparison of sensor performance, it was found that most sensors exhibit a high level of coherence and waveform similarity within a specific frequency range. Additionally, the experimental design and sensor reliability were critically evaluated, highlighting the urgent need for reliable reference sensors.

Summary: Using satellite data and a recent method to disentangle multiscale processes, it was found that wind deposits kinetic energy into the geostrophic ocean flow at scales larger than 260 km while removing energy from smaller scales, a process known as eddy killing. This process occurs at all times with seasonal variability, peaking in winter, and removes a substantial fraction of the wind power input in western boundary currents, serving as a major dissipation pathway for mesoscales, the ocean's most energetic scales.

Summary: Research on the transient variation processes of oceanic dissolved CO2 is significant due to the complexity and dynamics of the marine environment. However, the response performance limitation of in situ sensors poses challenges. This study presents a novel system solution that overcomes this limitation, enabling high-performance detection with a seconds-scale response, sub-ppmv level precision, and 3000 m rated depth. By improving the response performance of the sensor, the water mixing process and concentration variation profile can be accurately portrayed, offering insights into carbon cycle research in deep-sea unstable regions.

Summary: This study reports determinations of compressibility of the upper igneous crust of the Juan de Fuca plate, showing an azimuthal variation of compressibility by a factor of 5 across the structural fabric. This suggests a previously unresolved degree of fracturing of the uppermost oceanic crust, consistent with existing observations of high degree of hydraulic permeability anisotropy.

Summary: This study uses different data sources to analyze the various contributors to Arctic sea level variability. The study finds that the global sea level rise is the dominant factor influencing Arctic sea level changes, while Arctic oscillation, steric sea level increase, and intrusion of Pacific water also contribute to the variability. Additionally, the melting sea ice and larger open water area alter the impact of atmospheric forcing on Arctic sea level, with ocean dynamic circulation playing a more significant role.

Summary: In this study, the contributions to Arctic sea level (ASL) variability from different physical processes were quantified using Ocean Reanalysis System 5 (ORAS5) reanalysis data, tide gauge, and satellite altimetry observations. Results showed that the rising trend of ASL is primarily attributed to global sea level increase, Arctic Oscillation-induced mass redistribution, steric sea level increase in the Beaufort Gyre region, and intrusion of Pacific water into the Arctic Ocean. Furthermore, the impact of large-scale atmospheric forcing on ASL variability changed significantly after 1995 due to dramatic sea ice melting and increased open water area, with ocean dynamic circulation playing a more important role.

Summary: This paper discusses three algorithms for retrieving oceanic precipitation from brightness temperatures of the Micro-Wave Humidity Sounder-2 on Fengyun-3C satellite. The algorithms were validated by comparing the results with data from the Global Precipitation Climatology Project and Dual-frequency Precipitation Radar, showing consistent results.

Summary: This paper examines the estimation of angle of attack (AOA) for underwater gliders using an acoustic Doppler current profiler (ADCP) and proposes a regression method to estimate lift and drag coefficients. The results indicate that this method can be applied to any type of underwater glider equipped with an ADCP.
