Abstract. By utilizing Level 2A products (particle optical properties and numerical weather prediction data) 2C (numerical wind vector assimilated with observed component) provided by the Atmospheric Laser Doppler Instrument (ALADIN) onboard Aeolus mission, 2 vertical feature mask (VFM) Cloud-Aerosol Lidar Orthogonal Polarization (CALIOP) Infrared Pathfinder Satellite Observation (CALIPSO) three remote ocean areas are selected at 355 nm of marine aerosol derived. The combined analysis instantaneous co-located speeds above conducted. Eventually their relationships explored discussed two sperate atmospheric layers (0–1 km 1–2 km, correspond to heights within boundary layer (MABL)), revealing related background states. Pure obtained after quality control, cloud screening backscatter coefficient correction from ALADIN observations. spatial distributions speed study presented analysed, respectively, layers. statistical results along grids together corresponding regression curves fitted power law functions acquired for each area. present increasing trends in all cases, implying that atmosphere will both receive input produced transported turbulence. enhancement caused lower is more intensive than higher layer. As derived data ALADIN, averaged depth (AODmar) lidar ratio (LRmar) range. distributions, bins, variation tendencies individual not totally similar, development evolution might only be dominated drive wind, but also impacted other meteorological environmental factors, e.g., stability, sea air temperature, or relative humidity. Combined on additional parameters capable provide detailed information production, entrainment, transport removal.
