Course summary: Long-term continuous ground-based atmospheric observations are strongly constrained by land distribution and are still very limited over the sea, particularly in polar regions where fixed installations (buoys) are limited by sea ice. Ship-based atmospheric measurements can potentially close an important knowledge gap, particularly with the aim of validating satellite observations and atmospheric models. This course explores the challenges of taking atmospheric measurements on research ships. A team of experts will introduce and moderate a discussion of relevant topics, the opportunities arising from new technologies and concrete examples of best practices. The overall aim is to communicate the possibility of organizing research ships expeditions as multi-domain observing platforms, which is necessary if we want to elucidate the most important mechanisms and processes that drive the climatic system in the Arctic.
