Daily ocean temperature and salinity below the surface are difficult to observe but important for ocean monitoring and climate studies. We provide a three-dimensional dataset for the Northwest Pacific from 2021 to 2023, built from satellite observations and artificial intelligence. We highlight three advantages in our method: accuracy, timeliness and lightweight.

We created a new global dataset that reveals how ocean surface carbon dioxide has changed each month over the past four decades. By applying a deep learning model trained on both observational data and model simulations, we improved the representation of interannual variability and more accurately captured ocean responses to climate events like El Niño. This work supports global efforts to understand the ocean’s role in the carbon cycle and its response to climate change.

Large-scale wave modeling is essential for science and society, typically relying on resource-intensive numerical methods to simulate wave dynamics. In this study, we introduce a rolling AI-based method for modeling global significant wave height. Our model achieves accuracy comparable to traditional numerical methods while significantly improving speed, making it operable on standard laptops. This work demonstrates AI's potential to enhance the accuracy and efficiency of global wave modeling.

This study addresses the lack of comprehensive sea surface partial pressure of CO2 (pCO2) data in the North American Atlantic Coastal Ocean Margin (NAACOM) by developing the Reconstructed Coastal Acidification Database (ReCAD-NAACOM-pCO2). The product reconstructed sea surface pCO2 from 1993 to 2021 using machine-learning and environmental data, capturing seasonal cycles, regional variations, and long-term trends of pCO2 for coastal carbon research.

We overcame the limitations of satellite and reanalysis sea surface salinity (SSS) datasets and produced a gap-free gridded SSS product with reasonable accuracy and a spatial resolution of 1 km using a machine learning model. Our data enabled the recognition of SSS distribution and movement patterns of the Changjiang diluted water (CDW) front in the East China Sea (ECS) during summer. These results will further advance our understanding and monitoring of long-term SSS variations in the ECS.

Short summary
The Yellow Sea is known for its strong tidal and wind forcing that influence surface currents. However, traditional methods assume steady-state surface current, making it hard to capture effects of tide and typhoon. In this study, we developed a new method that considers inertia. By comparing our results with observations, we found that this approach provides improved accuracy compared to previous methods. This improvement can contribute to better understanding of dynamics in the Yellow Sea.
