Data sets

Optical profiles of continental and marine aerosol from lidar observations at Leipzig, Germany, and Mindelo, Cabo Verde Moritz Haarig et al. https://doi.org/10.5281/zenodo.15234831

Short summary

The lidar ratio is an important quantity in aerosol typing. Its spectral slope contains information about the source region or transport paths of the observed aerosol. The extension to 1064 nm is a recent development led by our institute. We gathered previous observations and added new ones to provide the spectral slope for the most important aerosol types such as marine and continental aerosol, dust, smoke, and sulfate. We compared it to assumptions used for spaceborne backscatter lidars.
