Research collaborators

Collaboration between the Degrees-funded research teams and experienced SRM scientists and scholars, is a crucial part of Degrees’ capacity-building process. While Degrees-funded scientists are experts in their own fields, few have worked on solar radiation modification (SRM) before. Each team is therefore paired up with at least one SRM expert, and they work together both in person and remotely over the duration of the project. Research collaborators volunteer their time and the relationship is intended to be mutually beneficial to both the collaborators and the Degrees-funded researchers.
