Geodetic GNSS data for atmospheric sounding recorded during the MOSAiC Expedition 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 RINEX data tracked by a top-side GNSS antenna installed at the compass deck of RV Polarstern. 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 in this dataset: - September 12-26, 2019 - June 3-8, 2020 - October 2-3, 2020
