Minute-averaged carbon dioxide dry air mole fractions measured at Met City during the 2019-2020 MOSAiC (Multidisciplinary drifting Observatory for the Study of Arctic Climate) expedition

This dataset contains ambient air minute-averaged carbon dioxide dry air mole fractions measured in the Central Arctic during the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition. The backbone of MOSAiC was the year-round operation of the Research Vessel Polarstern that drifted with the sea ice across the Central Arctic from October 2019 to September 2020. Measurements were performed on the sea ice itself from a 10 meter (m) flux tower at Met City (meteorological station housing numerous atmospheric measurements) located 300-600 m away from Polarstern.

本数据集收录了北极气候研究多学科漂流观测站（Multidisciplinary drifting Observatory for the Study of Arctic Climate，简称MOSAiC）科考活动期间，于北极中部地区测得的环境空气分钟平均二氧化碳干空气摩尔分数。此次MOSAiC科考活动的核心依托为“极星号”（Polarstern）科考船的全年运行任务，该船随海冰漂流，于2019年10月至2020年9月间横穿北极中部海域。测量工作在距离“极星号”300至600米的“气象城”（Met City，一座集成多项大气观测项目的气象站）的10米通量塔所在的海冰表面开展。
