The World Climate Research Programme (WCRP) invites applications for the position of Programme Manager for the International Project Office for Coordinated Regional Downscaling Experiment (CORDEX-IPO), to be hosted jointly by the European Space Agency (ESA) and University of Cape Town (UCT).

CORDEX goals are: 

• To better understand relevant regional/local climate phenomena, their variability and changes, through downscaling.
• To evaluate and improve regional climate downscaling models and techniques
• To produce coordinated sets of regional downscaled projections worldwide
• To foster communication and knowledge exchange with users of regional climate information

The Programme Manager you will be responsible for supporting coordination, planning, development, and implementation of the activities of CORDEX and leading on implementation of operations of the IPO as well as facilitating active CORDEX IPO liaison between the climate observations and modelling communities.

To know more about the position and to apply, see the details available in the call. Application closing date: May 30, 2026
