N2O Emissions From the Eastern Tropical Indian Ocean
Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.Abstract Nitrous oxide (N2O) is a potent greenhouse gas and major stratospheric ozone‐depleting compound. While 30% of global N2O emissions are attributed to the oceans, there are still large uncertainties partly due to sparse data coverage. The eastern tropical Indian Ocean is an under‐sampled area which potentially acts as a source of atmospheric N2O.

Arctic HYCOS – 1st Workshop on Improved Monitoring, Accuracy and Data Availability in the Arctic Drainage Basin: Meeting Summary Report and Implementation Plan [PDF]
, 2012 The World Hydrological Cycle Observing System (WHYCOS) is a global programme, developed in response to the scarcity or absence of accurate, timely and accessible data and information in real or near real time on freshwater resources in many parts of the ...

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.Abstract Poleward heat flux driven by large‐scale eddies is a widely recognized component of the general circulation. Although less known, a weak but persistent equatorward eddy heat flux (EEHF) also exists in the subtropical upper troposphere–lower stratosphere (UTLS).

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.Abstract The marine carbonate system plays a crucial role in regulating the global carbon cycle. In the North Pacific, the carbonate saturation depth (CSD), where biogenic calcium carbonate (CaCO3) starts to dissolve rapidly beneath, is suggested to be above ∼1,000 mbsl, contradicting with pervasive CaCO3 preservation in deep‐sea sediments.

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.Abstract During the 2023/2024 winter, eastern China experienced frequent cold extremes, heavy snowfall, and freezing rain, modulated by the circulation regime of enhanced atmospheric intraseasonal oscillation (ISO). Our results show these severe weather events can be attributed to two pathways of El Niño's influence.

Strongly Heterogeneous Surface‐Water Warming Trends in High Mountain Asia
Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.Abstract High Mountain Asia has experienced significant warming in recent decades. Changes in both temperature and precipitation patterns have strongly impacted regional hydrology, including changes to glaciers, snowmelt, and river systems. Here, we examine long‐term (1994–2023) and high‐resolution (30 m) changes in water‐surface temperature over a ...

Shallow and deep groundwater moderate methane dynamics in a high Arctic glacial catchment
Frontiers in Earth ScienceGlacial groundwater can mobilize deep-seated methane from beneath glaciers and permafrost in the Arctic, leading to atmospheric emissions of this greenhouse gas.

Simulated Greenland Surface Mass Balance in the GISS ModelE2 GCM: Role of the Ice Sheet Surface [PDF]
The rate of growth or retreat of the Greenland and Antarctic ice sheets remains a highly uncertain component of future sea level change. Here we examine the simulation of Greenland ice sheet surface mass balance (GrIS SMB) in the NASA Goddard Institute ...
