    Model analysis of biases in the satellite-diagnosed aerosol effect on the cloud liquid water path by H. Kokkola, H. Kokkola, J. Tonttila, S. M. Calderón, S. Romakkaniemi, A. Lipponen, A. Peräkorpi, T. Mielonen, E. Gryspeerdt, T. H. Virtanen, P. Kolmonen, A. Arola

    Published 2025-02-01
    “…We compare this correlation directly from the model to the correlation derived using equations which are used to retrieve liquid water path from satellite observations. Our comparison shows that spatial variability in cloud properties and instrumental noise in satellite retrievals of cloud optical depth and cloud effective radii results in bias in the satellite-derived liquid water path. …”
