Slide1
Synthesis of Climate Model Downscaling Products for the Southeast U.S.
Adrienne WoottenQED Workshop8/15/2013
Slide2“the
observations have problems, the global climate models are unreliable, the downscaling is unpredictable, and we have no idea which emissions scenarios to use, but go out and make decisions with climate projections
!”
But I still need to make decisions!
Slide3Motivation
Need data → increasing use → need to understand differences (practitioner’s dilemma)What datasets provideWhich datasets are more accurateClimate / Ecology ConnectionsFocus:
comparing and evaluating differences between available downscaled climate change products
Slide4Some SpecificsConsidering the Southeast
Specific to the needs of ecologistsNot just about which dataset is betterGuidance on which datasets to use and what to look for in others. Not a one time deal –
keep engagement going
Slide5Project Structure
Pick datasets Team includes climate scientists and ecologistsSteering committee of researchers and decision makersMetadata comparisonWorkshop 5/16 – 5/17/2013
Climatologists, ecologists, decision makersLearn from each other, how to tackle evaluationInitial evaluation – Summer 2013
Slide6About the Workshop
Regional Climate Variation and Change for Terrestrial Ecosystems Workshop Thoughts on what metadata is importantCommon metrics important to ecologistsMultiple levelsResearchers
Decision makersInformed evaluation
Slide7Lessons Learned
Variables of interest TemperaturePrecipitationWindsEvapotranspirationMeasures of Drought
Slide8Metrics – measures of variability, central tendency, extremesFrequency, intensitySpace / time location
Thresholds – lots of needs, depending on species, habitat, decision. Variables / Metrics were given but…Lessons Learned
Instead of individual thresholds – goodness of fit!
Slide9Lessons Learned
Two Important NotesData evaluation should be based on the decisions / study. Preference for access to experts not access to numbers.
Slide10Two Other thingsDesire for a finer resolution (1km)
Is it meaningful?Extra analyses in the mountains (topoclimatic models)Jargon be Gone!
Slide11As for the rest…
USGS Technical Report coming in Fall 2013More workshopsPotential for virtual collaboration and learning?
