Scientific visualisation is becoming an essential bridge between complex Earth system data and the general public, stakeholders, and decision-makers who need to understand and act upon it. This talk will present a portfolio of climate and environmental visualisations developed with Blender at the Earth Sciences Department of the Barcelona Supercomputing Center – Centro Nacional de Supercomputación (BSC-CNS). The presentation will show how high-resolution simulations, projections, and environmental datasets can be transformed into scientifically grounded visual narratives without losing rigour or traceability.
Examples will range from visualisations produced in the framework of the European Commission’s Destination Earth initiative—particularly its Climate Change Adaptation Digital Twin—where visualisation can help explore climate information in intuitive ways, such as comparing extreme events in the past, in the present, and under warmer future conditions, to air-quality visualisations developed within UrbanAIR, a European project working towards an urban air-quality digital twin for Barcelona and other cities.
The talk will also include additional examples related to climate change, atmospheric pollution, climate-sensitive infectious diseases, and the monitoring and quantification of greenhouse gas emissions.
In addition, the talk will show how 3D scientific visualisation can be extended beyond static outputs to support interactive, public-facing formats that make complex climate information easier for non-specialist audiences to engage with.
By sharing methods, examples, and lessons learned, the presentation will reflect on how Blender-based workflows can make climate data more accessible, meaningful, and actionable across scientific, institutional, and societal contexts.
