| Abstract: | The Arctic is changing rapidly with dramatic local and global effect. To understand that change requires understanding the
Arctic as a system. Models of different processes and at various scales are necessary tools for analyzing and understanding
the Earth system. Models are extremely diverse, yet they all require quality data. Through a series of case studies, augmented
with ethnographic observation around the International Polar Year, this work examines how modelers assess, acquire, and prepare
data for their models. By comparing specific case studies, common themes emerge that can be compared against broader observation.
These themes, in turn, suggest data management techniques or requirements for data systems to improve access and use by modelers
and generally improve understanding of the Arctic system. The study has an Arctic focus because of the rapid changes occurring
in the Arctic, but the approach and results should apply generally to Earth system science. This case study based approach
has proven to be a useful method for teasing out both general and specific data needs for different models. An overarching
lesson is that greater short-term benefit to modelers and significant gains in efficiency can be achieved by improving the
formats, convention, and consistency of the data rather than improved interfaces and analysis tools. A “data-first” philosophy
can improve the data systems that support the overall interdisciplinary, integrative science necessary to understand the complex
Earth system. |
