GNSS-based zenith total delays observed during the MOSAiC Campaign 2019-2020

During the transpolar drifting campaign MOSAiC (Multidisciplinary drifting Observatory for the Study of Arctic Climate) of RV Polarstern (AWI, 2017), GNSS was used among other techniques to monitor variations in atmospheric water vapor. This dataset comprises the estimated antenna position for each hour, the derived zenith total delays including their formal error and quality indicators. The GNSS equipment was installed on July 4th, 2019. For logistical reasons, the receiver was switched off on October 3rd at a position very close to Ny Ålesund, Svalbard. According to the MOSAiC data guidelines data for the following periods are not provided: - September 12, 2019 00:00 to September 26, 2019 12:40 - June 3, 2020 20:36 to June 8, 2020 20:00 - October 2, 2020 04:00 to October 2, 2020 20:00 - October 3, 2020 03:15 to October 4, 2020 17:00 The associated results are scientifically discussed in Männel et al. (2021)
