Initial radiosonde data from 2019-10 to 2020-09 during project MOSAiC

This is a Level 2 dataset of radiosondes launched during the MOSAiC expedition. The balloon-borne radiosondes measured temperature, pressure, relative humidity and wind from board R/V Polarstern to about 30 km height, commonly four times daily during the entire expedition period. The objective of Level 2 is to provide the user community with a usable data product before the final processed product is completed. Quality control for appropriate physical ranges has been applied. However, it should be noted that potential inconsistencies in the physical data in particular in the lowermost part of the profiles are not corrected. This regards e.g. GPS altitude close to the surface and wind direction at latitudes >89° N.

本数据集为 MOSAiC（多学科海洋大气综合研究）探险期间发射的二级无线电探空仪数据集。搭载于“极地星”研究船的气球式无线电探空仪测量了从船体至约30公里高度的温度、压力、相对湿度和风速，在整个探险期间，每日通常进行四次测量。二级数据集的目的是在最终处理产品完成之前，向用户群体提供可用的数据产品。已对适当物理范围进行了质量控制。然而，需要注意的是，特别是对于剖面最底层的数据，物理数据可能存在潜在的不一致性，这包括例如接近地表的GPS高度和北纬89°以上的风向等问题。
