2-Day Stakeholder workshop hosted by CLCC in San Juan to refine climate model output
IDEA IS TO HAVE CLIMATE PROJECTIONS THAT ARE SPECIFIC TO THE DECISION, BUT ALSO RELEVANT TO OTHER SCIENTIFIC/ ECOLOGICAL QUESTIONS
How could climate change affect shade coffee producWon? Providing public goods
Follow-up workshop in August 2016 to discuss available modeling outputs Providing public goods
Rank climate variables based on ecological significance Used this dialogue to help retain necessary climate model data
Downscaled Climate Variables
Exceeded 1 million CPU hours to accomplish the downscaling for just one of the regional climate models. We reduced ~1 Petabyte of model output to < 20TB with the knowledge of climate variables to retain from prior workshop
