    Continuous GNSS raw data measured from POLARSTERN deck during the MOSAiC expedition with POLARSTERN to the Arctic (2023)
    PANGAEA
    Details
    Publikationsdatum: 2024-04-20
    Beschreibung: Raw data acquired by a JAVAD Delta 3 GNSS Receiver with a resolution of 50Hz on board RV Polarstern during the MOSAiC expedition. The data is stored in JAVAD's .jps format (JAVAD GNSS, GREIS – GNSS Receiver External Interface Specification, San Jose, USA, 2022 (download available at https://www.javad.com/jgnss/support/manuals.html)). Each file contains data of one day with a typical file size of 1GB. The receiver was equipped with a multi-frequency GNSS antenna which was mounted on the ship’s observation deck. It has to be noted that the main mast and the ship’s chimney lead to a shadowing of GNSS observation links in at least two directions seen from the antenna position. The data was collected for measuring scintillation activitiy in the central arctic. Processed scintillation measurements with a 1 minute resolution are available (doi:10.1594/PANGAEA.956019).

    GNSS intermediate frequency data snippets measured from POLARSTERN deck during the MOSAiC expedition with POLARSTERN to the Arctic (2023)
    PANGAEA
    Details
    Publikationsdatum: 2024-04-20
    Beschreibung: GNSS intermediate frequency (IF) data samples acquired by the NTlab NT1065_USB3 Front End. The samples are collected with a sampling rate of 99.375MHz at IF for four GNSS Bands: GPS L1 (1575.42 MHz), GLONASS L1 (1602 MHz), Galileo E5b (1207.14 MHz), Galileo E5a (1176.45 MHz) with a resolution of 2 bit (for detailed file description see readme.txt). The front end was equipped with a multi-frequency GNSS antenna which was mounted on the ship's observation deck. It has to be noted that the main mast and the ship's chimney lead to a shadowing of GNSS observation links in at least two directions seen from the antenna position. The data was collected for measuring GNSS IF data in the central Arctic. For that purpose data was periodically collected during the whole MOSAiC expedition (files labeled with 'fperiodic'). Moreover, it was desired to collect date during scintillation events. The files labeled with fevent are collected during periods of increase scintillation index as provided by processed GNSS raw data (doi:10.1594/PANGAEA.956019).

    Lead classification maps from helicopter-borne surface temperatures with 1 m resolution during the MOSAiC expedition (2022)
    PANGAEA
    Details
    Publikationsdatum: 2024-04-20
    Beschreibung: Leads (open water and thin ice) were classified in helicopter-borne thermal infrared observations. Lead classification maps, gridded in 1 m resolution, are provided for 35 flights between 02.10.2019 and 23.04.2020 during the MOSAiC expedition in the Arctic ocean. There is one file for every flight, either on a local (MOSAiC central observatory) or regional scale (MOSAiC distributed network). The flights can be identified by two campaign specific IDs (the event-related Device Operation label or Flight ID). The lead classification maps are derived from the surface temperature maps (doi:10.1594/PANGAEA.941017) as described in Thielke et al (in preparation). The 5 m resolution data (based on block averaged surface temperature) are included to provide data with a smaller file size so they are easier accessible and available for the comparison of the effect of different spatial resolutions. The binary lead classification is performed with a temperature threshold. In this data set, in addition to the lead classification maps, also the surface temperature and time-fixed surface temperature maps are included (the same data as included in the temperature maps: doi:10.1594/PANGAEA.941017). This time-fixed surface temperature is necessary to perform the classification and included for direct comparison to the lead classification result. All data are georeferenced, also as relative coordinates to the position of RV Polarstern which allows a Polarstern centered, Lagrangian view on the lead development.
