ACE Technical Overview Paul Meyer, ACE Systems Engineer Rob Cermak, ARSC Life Sciences Informatics Support 1

ACE Design - Guiding Principles ACE is an open sourced, internet-based, open-access, Arctic-focused, environmental research and decision- support system that integrates data from existing remote sensing assets, products from existing and new environmental models, and in-situ reporting to provide monitoring, analysis, and visualization based on earth observation data and modeling. These products may be layered within an embedded KML- compliant viewer (e.g., Google Earth) and integrated into a community-based collaborative environment, as well as exposed through an Application Programming Interface (API). 2
