Specially-appinted researcher,Center for Environmental Remote Sensing（work on studies of climate tipping reconstruction）

Job description

Background of the recruitment and description of the project

[Job Description]

Chiba University invites applications for a researcher to work on studies of climate tipping reconstruction.

Work content and job description

Climate tipping points involve large uncertainties in their prediction. This project focuses on the weakening and collapse of the Atlantic Meridional Overturning Circulation (AMOC), aiming to identify key sources of uncertainty and underlying mechanisms by integrating paleoclimate proxies with climate models using data science approaches.

The successful candidate will be expected to:

• Develop model-data integration frameworks linking climate model outputs with paleoclimate proxies
• Perform uncertainty quantification and parameter estimation using methods such as Bayesian optimization
• Conduct paleoclimate reconstructions using data assimilation
• Investigate tipping mechanisms and early warning indicators through numerical experiments

The project ultimately aims to constrain the predictability of climate tipping points and provide guidance for improved modeling and observational strategies.
