C3 a brief presentation

The Centre for Climate Change (C3), set up in late 2008 at the Campus de les Terres de l'Ebre by the University Rovira i Virgili (Tarragona, Spain), is focused on researching, outreaching and knowledge transferring in the fields of climate reconstruction and analysis. The specific activities include high-quality climate datasets development (comprising data rescue procedures and research on homogenization methods) and climate variability and change assessments (particularly climate change detection) at different spatial (from local to global) and temporal (from sub-daily to annual) scales.
