Short summary
Clouds strongly affect how sunlight and heat move through the atmosphere, but their vertical layers make them hard to study. We examined how different cloud layers influence satellite estimates of cloud thickness and droplet size using observations and computer simulations over China. We found that high ice clouds can hide lower water clouds, causing large errors. This shows satellites need to consider cloud layers to improve accuracy.
