Accurate climate modelling and prediction are essential for understanding climate change impacts, optimising water resource management, and mitigating drought and flood risks. However, simulations of extreme precipitation and high‐temperature events remain highly uncertain due to the strong sensitivity of regional climate models to physical parameterisation schemes and the lack of systematic identification of optimal scheme co...

Nitrous oxide in the surface water was measured using an automatic underway system, along with measurements of surface water pCO 2 , dissolved oxygen, salinity, temperature, and sea ice coverage, along a cruise track through the Bering Sea and Chukchi Sea to the Canadian Basin during the 7 th Chinese National Arctic Research Expedition. The results show that, overall, the regions along the cruise track are net sources of N 2 O...
