🎉 Congratulations, Dr. Sinikka Paulus (@spaulus.bsky.social) ! 🎓

This past September, Sinikka successfully defended her PhD thesis titled:

"A Novel Framework for Assessing the Spatiotemporal Dynamics of Soil Water Vapor Adsorption Using a Global Observation Network"!

How Can We Redefine Natural Hazards Through Societal and Health Responses? In this video, KELLEY DE POLT argues for a more integrated understanding of natural hazards by linking extreme heat events with societal interest and public

💡 I had the opportunity to speak with LATEST THINKING (lt.org) about ongoing work throughout my PhD that incorporates societal and health responses into natural hazard risk assessments.

In this study, we determine the relevance of atmospheric drivers, such as wind, geopotential height, horizontal geopotential height differences, and surface net radiation, and land surface drivers, such as evaporative fraction and enhanced vegetation index, for hot extremes across the globe. 🌱☀️🌍

Global relevance of atmospheric and land surface drivers for hot temperature extremes Abstract. Hot temperature extremes have severe impacts on society and ecosystems. These extremes are driven by both atmospheric and land surface processes, such as advection or reduced evaporative coo...

New paper from our group in Earth System Dynamics!

We find geopotential height is the main driver of hot extremes. ☀️ Surface net radiation and evaporative fraction are secondary daily drivers, while 🪁 wind dominates weekly.

Exciting workshop ahead for some of our group members in Monte Verita next week 02.03 - 07.03:
“Missing links in drought research: linking plant physiology, soil hydrology, and climate science across scales”💦🌳
Thanks to the organizers of this great event!
Join us at our contributions!

Special thanks to the supervision team (@kdepolt.bsky.social, René Orth, & @aschweiger.bsky.social ) and the members of the @hydrorth-lab.bsky.social group for their guidance, mentoring, valuable feedback and discussions.

We are excited to share the successful defence of Metin Ilke Özcan’s Master's thesis, titled 'Quantifying Impact-Relevant Timescales of Droughts on Vegetation.' The research explores the importance of selecting appropriate timescales and definitions when assessing drought impacts. 🌳🌲

Disentangling Effects of Vegetation Structure and Physiology on Land–Atmosphere Coupling This study investigates the regulation of vegetation structure and physiology in land-atmosphere interactions. Using an explainable machine learning approach, we quantify the importance of leaf area ....
