Large anomalies in future extreme precipitation sensitivity driven by atmospheric dynamics. [PDF]
Nat Commun, 2023 Increasing atmospheric moisture content is expected to intensify precipitation extremes under climate warming. However, extreme precipitation sensitivity (EPS) to temperature is complicated by the presence of reduced or hook-shaped scaling, and the ...

AtmoDist: Self-supervised representation learning for atmospheric dynamics [PDF]
Environmental Data Science, 2022 Representation learning has proven to be a powerful methodology in a wide variety of machine-learning applications. For atmospheric dynamics, however, it has so far not been considered, arguably due to the lack of large-scale, labeled datasets that could

Impacts of aerosol direct effects on tropospheric ozone through changes in atmospheric dynamics and photolysis rates. [PDF]
Atmos Chem Phys, 2017 Aerosol direct effects (ADEs), i.e., scattering and absorption of incoming solar radiation, reduce radiation reaching the ground and the resultant photolysis attenuation can decrease ozone (O3) formation in polluted areas.

Ocean Ammonia Outgassing: Modulation by CO2 and Anthropogenic Nitrogen Deposition
Journal of Advances in Modeling Earth Systems, 2020 The imprint of anthropogenic activities on the marine nitrogen (N) cycle remains challenging to represent in global models, in part because of uncertainties regarding the source of marine N to the atmosphere.
