中国第9次南极科学考察(1992-1993)南大洋走航自动气象观测数据

南极地区和南大洋海域是全球气候变化的关键区域，开展南极地区近海/冰面海洋气象观测，可以得到南极地区气候气候变化的第一手数据，对于进一步研究南极地区气-海-冰相互作用，加深对南极气候变化的理解具有重要科学价值。
本数据为中国9次南极科学考察走航自动气象站观测数据
对了解南极及周边海域海洋气象最新状况，加深对南极地区气-海-冰相互作用机制的理解、研究南极气候变化具有重要意义。
1.测量仪器
“雪龙”号船载自动气象站。
2.观测方法和所获观测资料
1992年10月31日-1993年4月2日，自动气象站走航自动观测，观测要素包括经度、纬度、艏向、船速、气压、气温、相对湿度、露点温度、风向、云量等信息。

The Antarctic region and the Southern Ocean are key areas for global climate change. Conducting marine meteorological observations over the nearshore/sea ice surface of the Antarctic region can obtain first-hand data on Antarctic climate change, which is of great scientific value for further studying the atmosphere-sea ice-ocean interaction in the Antarctic region and deepening the understanding of Antarctic climate change.

This dataset contains observational data from underway automatic weather stations deployed during 9 Chinese Antarctic Scientific Expeditions.

It is of great scientific significance for understanding the latest marine meteorological conditions over Antarctica and its adjacent waters, deepening the comprehension of the atmosphere-sea ice-ocean interaction mechanisms in the Antarctic region, and conducting research on Antarctic climate change.

1. Measuring Instruments
Shipborne automatic weather station onboard the Xuelong icebreaker.

2. Observation Methods and Collected Observational Data
From October 31, 1992 to April 2, 1993, the automatic weather station carried out underway automatic observations. The observed elements include longitude, latitude, bow heading, ship speed, atmospheric pressure, air temperature, relative humidity, dew point temperature, wind direction, cloud cover, and other relevant information.
