Recent paper on volcanic eruptions and wind energy featured on the cover of The Innovation
A recent paper co-authored by Hans Chen is featured on the cover of the relatively new open-access journal The Innovation. The paper, led by Cheng Shen, investigates the effect of strong tropical volcanic eruptions on near-surface wind speed globally.

Wrapping up 2024 with new papers
Happy 2025! We close out 2024 on a high note with some new exciting research:
Machine learning and aerosols:
- Yan et al. (2024): Deep learning with pretrained framework unleashes the power of satellite-based global fine-mode aerosol retrieval.
- Yan et al. (2024): Substantial underestimation of fine-mode aerosol loading from wildfires and its radiative effects in current satellite-based retrievals over the United States.
Carbon cycle and ecosystem dynamics:
- Xu et al. (2024): Global patterns and drivers of post-fire vegetation productivity recovery.
- Li et al. (2024): Increasing sensitivity of tree radial growth to precipitation.

New paper investigating the effects of vegetation physiological response on climate zone shifts
We have recently published a paper that investigates how global Köppen–Geiger climate zones are projected to shift under 4×CO2, with a special focus on the effect of vegetation physiological changes, which have been largely neglected so far. You can find the paper in Science of The Total Environment:
- He et al. (2024): Vegetation increases global climate vulnerability risk by shifting climate zones in response to rising atmospheric CO2.

Increased land precipitation due to enhanced evaporation from the Arctic: new paper in npj Climate and Atmospheric Science
Our new paper investigates how the enhanced evaporation due to sea-ice retreat in the Arctic has contributed to cold season land precipitation over the Northern Hemisphere during 1980–2021. Moisture tracking suggests that additional evaporation from the Arctic marginal seas has contributed to a 32% increase in land precipitation, corresponding to a 16% increase per million square km sea-ice area loss.
