    • Main Results:

    • Heating times are highly dependent on particle radii and layer position.
    • Shell thickness, particularly of the surface carbon layer, significantly affects heating duration.
    • A thinner surface carbon layer leads to reduced heating times.

    Conclusions:

    • The heating dynamics of multilayer particles are complex and influenced by multiple factors.
    • Controlling the thickness of constituent layers, especially the carbon shell, offers a method to manage heating rates.
    • These findings have implications for lidar applications and understanding atmospheric particle behavior.
