The scope of the workshop will include predictability and prediction from weather to climate timescales across Earth system components (atmosphere, ocean, land, sea-ice, geospace, terrestrial and marine ecosystems), spanning timescales of minutes to days, subseasonal to seasonal, seasonal to decadal, and decades to centuries. Workshop participants will be involved in establishing key scientific questions, discussing needs for community modeling and analysis tool capabilities, better integration of observations and modeling, stakeholder engagement, and identifying partnership opportunities with the community.
