Global atmospheric boundary layer wind speed profile dataset derived from Aeolus observations from July 2020 to April 2023

Global-ABLWind is a global atmospheric boundary layer (ABL) wind speed profile dataset based on the first spaceborne LiDAR Aeolus covering the height range from 100 m to 2000 m above ground level at 100 m vertical resolution, spanning the period from July 2020 to April 2023. The Aeolus has two receivers that simultaneously capture the signal from both the Rayleigh (Ray) and Mie channels. Similarly, this dataset also includes two versions based on Aeolus observations from different channels The temporal and spatial resolution is identical to that of the Aeolus L2C product. The dataset is distributed as monthly NetCDF files, with filenames following the convention "Global-ABLWind_XXX_V1_YYYY_MM.nc", where XXX represents the channel (Ray or Mie), YYYY refers to the year, and MM is the month of the year. standard_name (Variable name) Dimensions Units Description time 1 seconds since YYYY-MM-01 00:00:00 Average time of Aeolus observations used for the current wind profile, derived from the Aeolus L2C product latitude 1 degrees_north Average latitude of Aeolus observations used for the current wind profile, derived from the Aeolus L2C product longitude 1 degrees_east Average longitude of Aeolus observations used for the current wind profile, derived from the Aeolus L2C product height 1 m Height above ground level (AGL), fixed vertical grid from 100 m to 2000 m at 100 m intervals wind_speed (ws) 2 m s⁻¹ Horizontal wind speed
