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.
