Harmonised boundary layer wind profile dataset from six ground-based doppler wind lidars in a transect across Paris, France
Abstract. Doppler wind lidars (DWL) offer high-resolution wind profile measurements that are valuable for understanding atmospheric boundary layer (ABL) dynamics. Here six ground-based DWL, deployed in a multi-institutional effort along a 40 km transect through the centre of Paris (France), are used to retrieve horizontal wind speed and direction through the ABL at 18–25 m vertical and 1–60 min temporal resolution. Data are available for June 2022 – March 2024 (three DWL) and two Intensive Observation Periods (six DWL) across 9 weeks in September 2023 – December 2023. Data from all sensors are harmonised in terms of quality control, file format, as well as temporal and vertical resolutions. The quality of this DWL dataset is evaluated against in-situ measurements at the Eiffel Tower and radiosonde profiles. This unique, spatially dense, open dataset will allow urban boundary layer dynamics to be explored in process-studies, and is further valuable for the evaluation of high-resolution weather, climate, inverse and air pollution models that resolve city-scale processes.

Review of the ESSD manuscript 2025-167 “Harmonised boundary layer wind profile dataset from six ground based doppler wind lidars in a transect across Paris, France”
The presented topic of the manuscript is very interesting and relevant for atmospheric boundary layer research in urban environments. The final harmonized and open data set of boundary layer wind profiles is quite valuable for the research community and opens new pathway for process based studies and evaluation of atmospheric models for urban applications.
Specific comments:
Line 62: “The harmonisation process involves application of wind retrievals from …” Do you refer to application of certain wind retrieval algorithms?
Line 88: “… scanning configurations with the following parameters: azimuth (θ) and zenith (φ) emission angles of the laser” is good but table 3 presents horizontal wind scan type with elevation angle e.g. VAD 75°, please add information that refers to this angle
Line 233: „Päschke et al.’s (2015) retrieval method“: Did you applied default values of configuration file or did you changed certain parameter settings e.g. for CNS_PERCENTAGE? Please provide config files if possible.
Line 322: GPS position is updated every 1s?
Figure 1: Please provide the time period of the presented wind rose measured at the Tour Eiffel
Figure 2a: The figure capture states “ordered from north-east to south-west”, this is true if we look from the bottom panel to the top panel. But not the other way around. May better: “ordered from north-east (lower panel) to south-west (upper panel).
Figure 2b: The horizontal lines for the very low altitudes are bit confusing. These lines show that below at a certain altitude e.g. 100 m are no data? This corresponds to the lowest reasonable gate?
Table 1: City centre (CC) is given as reference, please provide latitude and longitude. The abbreviation LMD means?
Table 2: No table entry means “not available” e.g. for the “Radial wind accuracy” or something else?
