An underestimated negative cloud feedback from cloud lifetime changes

J Mülmenstädt, M Salzmann, JE Kay… - Nature Climate …, 2021 - nature.com
As the atmosphere warms, part of the cloud population shifts from ice and mixed-phase
('cold') to liquid ('warm') clouds. Because warm clouds are more reflective and longer-lived …

Influence of biogenic emissions from boreal forests on aerosol–cloud interactions

T Petäjä, K Tabakova, A Manninen, E Ezhova… - Nature …, 2022 - nature.com
Boreal forest acts as a carbon sink and contributes to the formation of secondary organic
aerosols via emission of aerosol precursor compounds. However, these influences on the …

Opinion: Tropical cirrus–from micro-scale processes to climate-scale impacts

B Gasparini, SC Sullivan, AB Sokol… - Atmospheric …, 2023 - acp.copernicus.org
Tropical cirrus clouds, ie, any type of ice cloud with tops above 400 hPa, play a critical role in
the climate system and are a major source of uncertainty in our understanding of global …

General circulation models simulate negative liquid water path–droplet number correlations, but anthropogenic aerosols still increase simulated liquid water path

J Mülmenstädt, E Gryspeerdt, S Dipu… - Atmospheric …, 2024 - acp.copernicus.org
General circulation models'(GCMs) estimates of the liquid water path adjustment to
anthropogenic aerosol emissions differ in sign from other lines of evidence. This reduces …

Spatial aggregation of satellite observations leads to an overestimation of the radiative forcing due to aerosol‐cloud interactions

T Goren, O Sourdeval, J Kretzschmar… - Geophysical Research …, 2023 - Wiley Online Library
The estimation of cloud radiative forcing due to aerosol‐cloud interactions, RFaci (also
known as the first indirect effect), relies on approximating the cloud albedo susceptibility to …

The prevalence of precipitation from polar supercooled clouds

I Silber, AM Fridlind, J Verlinde… - Atmospheric …, 2021 - acp.copernicus.org
Supercooled clouds substantially impact polar surface energy budgets, but large-scale
models often underestimate their occurrence, which motivates accurately establishing …
