The Arctic is the region where global climate change is most pronounced, featuring the "Arctic Amplification" effect. Conducting offshore/sea-ice marine meteorological observations in the Arctic can obtain first-hand data on Arctic climate change, which holds important scientific value for further research on air-sea-ice interactions in the Arctic and deepening the understanding of the Arctic Amplification effect.

This dataset comprises transit manual meteorological observation data from the 13th Chinese National Arctic Research Expedition (2023). It is of great significance for understanding the latest status of marine meteorology in the Arctic and its adjacent seas, deepening the understanding of the air-sea-ice interaction mechanisms in the Arctic, and studying the Arctic Amplification effect and its relationship with extreme weather and climate events in China.

1. Measuring Instruments
Xuelong 2's shipboard Vaisala automatic weather station

2. Observation Methods and Collected Observation Data
From July 12 to September 26, 3 to 4 manual routine transit marine meteorological observations were conducted daily at Universal Time (UT) 00:00, 06:00, 12:00, and 18:00, in accordance with the national standards *Specification for Oceanographic Survey, Part 3: Marine Meteorological Survey* and *Technical Specifications for Polar Marine Hydrometeorological, Chemical and Biological Surveys*. Besides the meteorological elements measured by the automatic weather station, the observation items also include weather phenomena, cloud amount and cloud type, wave height and swell height.
