PIMMS - Pinatubo Interdisciplinary Multi-Model Study

The eruption of Mount Pinatubo was the largest explosive volcanic eruption to have occurred during the recent period of intensive atmospheric measurements, and provides an iconic target for Earth System modelling because the cascade of impacts that occurred deeply involved the physical climate, terrestrial and marine ecosystems, and atmospheric chemistry. This Working Group brought together QUEST modellers and data experts from each domain to design and carry out linked model experiments, with the intention to clarify the Earth System consequences of the eruption, and thereby to gain insights into the system’s response to a significant perturbation to its boundary conditions.

The Working Group brought together the various Theme 1 projects in QUEST around a common scientific goal. It also anticipates future developments by scoping the kinds of "fully coupled" model experiments that will become possible when the QUEST Earth System Model (QESM) has been built.
