TEAMx: Doppler Wind Lidar data (WindCube 100S), Radfeld, Austria

Context and Overview As part of the TEAMx campaign, a Vaisala Windcube WCS100S was deployed in Radfeld (Inn Valley Target Area, IVTA), Austria from 23 October 2024 to 8 September 2025. More information on TEAMx can be found here. Here, we provide the complete raw dataset from the Doppler wind lidar deployed during the campaign in Radfeld, Austria. Wind lidar type: WCS100S (Leosphere WindCube)Location: 47.458999, 11.932239 (Radfeld, Austria)Altitude: 510 m a.s.l.Deployment time: 23 October 2024 to 8 September 2025Data are provided from 6 November 2024 to 8 September 2025 (see logbook for details) Owner: Federal Office of Meteorology and Climatology MeteoSwiss, SwitzerlandContact: Rebecca Gugerli, Maxime Hervo If you have any questions about the dataset, please do not hesitate to contact us. Overview of DBS scans To provide an overview, we compiled the monthly availability as a function of altitude and provide plots of monthly wind roses at given altitudes. Please find these figures as pdfs in the uploaded dataset and a more detailed description below. Availability plots These figures show the availability (%) per gate at a monthly resolution at Radfeld. A full profile is available every couple of minutes (netcdf file), which contains several profiles of wind speed and direction (obtained every couple of seconds). Wind speed and -direction are obtained by the Vaisala retrieval algorithm. After applying the quality flags, valid hours are only counted if at least 25% of measurements (at the highest temporal resolution) are available. Over the entire measurement period, approximately 95% data availability was achieved at the lowest measurement gate. The 50% data availability height is around 2400 m a.s.l. The main reason for not achieving 100% availability at the lowest altitude is the occurrence of measurement gaps (see logbook). Wind rose plots The wind roses provide a useful overview of the prevailing wind conditions. They are derived for a set of altitudes (710 m a.s.l., 1510 m a.s.l., 2010 m a.s.l., 3010 m a.s.l. and 5010 m a.s.l.). Please note that the center of the first measurement gate is located 200 m above ground level (AGL), which results in an altitude of 710 m a.s.l. Data Acquisition and Dataset Organization Logbook The Doppler wind lidar was deployed on 23 October 2024. However, a directional offset was identified and corrected on 6 November 2024. Please note that these data are not provided here, but can be provided upon request. The lidar was dismounted on 8 September 2025. 23.10.2024 Deployment of Doppler wind lidar 6.11.2024 10:45 UTC Improvement of directional offset with hard target calibration 06.11.2024 11:00 UTC - Begin of high quality & directionally calibrated measurements 03.12.2024 15:00 UTC - Change of scan strategy (more PPI’s, less DBS and RHI’s) 08.01.2025 05:00 UTC - 08.01.2025 09:00 UTC no data available (reason not clear) 12.03.2025 09:00 UTC - 12.03.2025 12:30 UTC no data available (reason not clear) 14.05.2025 09:00 UTC - 15.05.2025 08:00 UTC no data available (reason not clear) 12.06.2025 08:00 UTC - Change of scan strategy (alignment with other devices from the TEAMx campaign) 01.07.2025 19:00 UTC - 09.07.2025 18:00 UTC no data due to full HDD & connection issues 09.07.2025 17:45 UTC - HDD cleaned and measurements restarted 04.08.2025 11:15 UTC - 04.08.2025 13:30 UTC no data (reason not clear) 08.09.2025 05:00 UTC Last observation before dismantling the lidar system Scanning modes During the campaign, the scanning modes DBS, RHI and PPI were used. A short description of these modes is presented below. DBS: Doppler Beam Swinging, provides 3D wind fields. PPI: Plan Position Indicator, provides radial wind speed measurements at a fixed elevation angle for all azimuth angles. RHI: Range Height Indicator, provides radial wind speed measurements at a fixed azimuth angle over all elevation angles. File naming As an example, we use this filename: WLS100S-101_2025-02-04_00-01-24_ppi_174_100m.nc.gz, which can be decomposed as follows: WLS100S-101_2025-02-04_00-01-24_ppi_174_100m.nc.gz --> Wind lidar type and serial number WLS100S-101_2025-02-04_00-01-24_ppi_174_100m.nc.gz --> Time stamp (UTC) WLS100S-101_2025-02-04_00-01-24_ppi_174_100m.nc.gz --> Scanning mode (dbs, ppi or rhi) WLS100S-101_2025-02-04_00-01-24_ppi_174_100m.nc.gz --> Scan configuration ID WLS100S-101_2025-02-04_00-01-24_ppi_174_100m.nc.gz --> Scan resolution Housekeeping The housekeeping files of the lidar system (file name WLS100S-101_environmental_data_YYYY-MM-DD_HH-MM-SS.csv) contain additional information on GPS position (constant for all timestamps) Levelling of the lidar (roll and pitch) Internal temperature and relative humidity (incl. dew point) Acknowledgements A successful field campaign is the result of the efforts of many people working behind the scenes. We would like to thank the Klärwerk in Radfeld who allowed us to deploy the lidar on their premise and provided support during interventions on site. We thank the remote-sensing technical and administrative team at MeteoSwiss for preparing (incl. custom documents), deploying and dismantling the lidar system. Last but not least, we thank Alexander Gohm, Philipp Vettori and Beth Saunders from the University of Innsbruck for their help during the deployment and on-site troubleshooting.
