The presentation is divided into two major components . First , I will give an overview of space weather phenomenon and their associated impacts . Then I will describe the comprehensive list of products and tools that NASA Space Weather Center has developed by leveraging more than a decade long modeling experience enabled by the Community Coordinated Modeling Center ( CCMC ) and latest scientific research results from the broad science community . In addition , a summary of the space weather activities we have been engaged in and our operational experience will be provided .
