Trans experiment (FLOW) - raw lidar data

This dataset contains the raw lidar measurements from the Trans experiment which was part of the EU FLOW project [1]. It covers the entire span of the campaign and includes all data from all range gates of each lidar. Data from all the five lidars and ceilometer have been segregated and the corresponding files are named according to the aliases in read_me.txtDue to the large size, the archive of each lidar has been split into parts of 4 GB.We recommend the following steps in order to read/access the data:Download all the tar files into a local repository. (Note that after decompressing, the total size of the dataset will be approximately 2 TB).Run cat .tar.xz.part* > .tar.xztar -xJf .tar.xzUse the functions from the notebook WES_data_paper_NB.ipynb (here) to read data for a particular range gate and period of time. Since the data storage format differs based on the lidar model, there are three different functions pertaining to the three different lidar models used in the experiment.Note that the processed ceilometer data can be accessed from DTU's SQL server:Server: data02.windenergy.dtu.dk (130.226.56.234, MySQL version 5.6.51 on port 3306)Username: flowuserPassword: FlowDataReaderAnd a processed subset of the lidar data can be accessed via: https://doi.org/10.11583/DTU.28390181.v1Reference:Mann, Jakob, Sjöholm, Mikael, Patel, Ansh, Thorsen, Gunhild Rolighed, Simon, Elliot, Hung, Lin-Ya & Gottschall, Julia 2025 Lidar measurements of turbulence in the marine atmospheric boundary layer.
