Witryna3 mar 2024 · The decreasing lofting rate is well captured by the simulations (when using the 1.5 × CALIOP AOT parameterization), and the final height at 30 km after 2 months is in good agreement with the observations. This shows that our ECRAD-based simulation scheme can reproduce the observed lofting rates of the smoke plumes.
