Spectral data from continuous observations by CDWL on 19 June 2024

The present data are the raw spectral data obtained by CDWL on 19 June 2024 from continuous observations of radial wind speeds in the range of 52 m to 6 km horizontal distance near the ground at a low elevation angle of 3 degrees. The data are mainly used to validate the newly developed image preprocessing-based algorithm for estimating the Doppler spectrum from the spectral data in order to improve the detection performance of CDWL under low signal-to-noise ratio conditions.
