The US CLIVAR Water Isotopes and Climate Workshop will be held from 1-3 October 2019 in Boulder, Colorado, USA.

The theme is "Advancing the application of water isotope tracers to climate science with observations and modeling".

Many of today’s grand challenges in climate science revolve around the water cycle. How sensitive are low-level clouds to climate variations? How do large-scale precipitation patterns and extremes evolve with natural and anthropogenic forcings? How do shifts in the hydrological cycle affect ecosystem structure and function, and vice versa?

Water isotope ratios are powerful tools for uncovering the mechanisms driving past, present, and future changes in the global water cycle. With the ability to "tag" moisture as it travels through the atmosphere, ocean, biosphere, and cryosphere, isotopes ratios provide insights into key processes that shape regional to global hydrological variability. The preservation of water isotopes in a diverse array of proxy records makes them an important bridge between past and present climate variability, with key implications for future climate change impacts.

Join this workshop to develop new strategies for applying isotope ratios towards understanding and predicting the water cycle’s role in climate variability and change.


Workshop topics are likely to include (but are not limited to):

- Performing paleoclimate data model comparisons for water-isotope based proxy systems, including paleoclimate data assimilation schema
- Improving observational networks for water isotopes in the ocean, biosphere and atmosphere
- Challenges and advantages of incorporating stable water isotope physics in GCMs
- Using water isotopes to evaluate and improve model physics and parameterizations
- Understanding the relationship between water isotopes and the large-scale circulation of the atmosphere and ocean
- Evaluating atmosphere-land surface and atmosphere-biosphere interactions
- Investigating the global hydrologic cycle, including continental recycling and atmospheric moisture transport
- Elucidating the roles of water vapor, clouds, and precipitation processes in controlling climate sensitivity
- Understanding internal climate variability from sub-seasonal to centennial time-scales
- Integrating paleoclimate data sets with modern observations and climate models toward improved understanding of climate variability and change

Target participants

Whether you currently work with isotopic tracers or not, if you are interested in climate-related questions with a direct water cycle link, come help identify the most effective ways to make progress in understanding and predicting water cycle variability and change by applying new isotopic measurement and modeling techniques. One of the workshop’s goals is to bring together a broad group of researchers, including observationalists and modelers, from across various climate-related disciplines. The workshop encourages the participation of scientists internationally.
