中国第13次北极科学考察(2023年)走航自动气象站观测数据

北极地区是全球气候变化最明显的区域，存在“北极放大效应”。开展北极地区近海/冰面海洋气象观测，可以得到北极地区气候气候变化的第一手数据，对于进一步研究北极地区气-海-冰相互作用，加深对北极放大效应的理解具有重要科学价值。
本数据为中国第13次北极科学考察(2023年)走航自动气象站观测数据
，对了解北极及邻区海域海洋气象最新状况，加深对北极地区气-海-冰相互作用机制的理解、研究北极放大效应及其与我国极端天气气候事件的关系具有重要意义。
1.测量仪器
雪龙2号船载维萨拉自动气象站
2.观测方法和所获观测资料
7月12日至9月26日，自动气象站走航自动观测，观测要素包括气温、相对湿度、露点温度、海平面气压、风向、风速、能见度和辐射。
3.观测区域
本航次考察海区，包括楚科奇海、加克洋中脊、北冰洋中心区。

The Arctic is the region where climate change is most pronounced, featuring Arctic Amplification. Conducting marine meteorological observations over Arctic offshore and sea ice areas can obtain first-hand data on Arctic climate change, which is of great scientific value for further studying atmosphere-sea-ice interactions in the Arctic and deepening the understanding of Arctic Amplification.

This dataset comprises the underway automatic meteorological station observation data from the 13th Chinese National Arctic Research Expedition (2023). It holds significant importance for understanding the latest marine meteorological conditions in the Arctic and its adjacent seas, deepening the comprehension of the mechanism behind Arctic atmosphere-sea-ice interactions, and researching Arctic Amplification and its correlation with extreme weather and climate events in China.

1. Measuring Instruments
Vaisala automatic meteorological station onboard the Xuelong 2 polar research vessel.

2. Observation Methods and Collected Observation Data
From July 12 to September 26, the automatic meteorological station conducted underway automatic observations. The observed elements include air temperature, relative humidity, dew point temperature, sea level pressure, wind direction, wind speed, visibility, and radiation.

3. Observation Area
The survey sea areas of this voyage cover the Chukchi Sea, Gakkel Ridge, and the central Arctic Ocean.
