Air Quality Policies and Science Challenges in GEO-CAPE Horizon
The policies in play during the GEO-CAPE Horizon encompass a range of Clean Power Plans, NAAQS requirements, emissions controls for vehicles, air toxics reduction strategies, and more. Science challenges include emissions quantification, atmospheric composition analysis, air quality and climate linkages, exposure estimation, and real-time information needs.

How can the GEO How can the GEO- -CAPE community further prepare to CAPE community further prepare to identify and address these challenges? identify and address these challenges? What have we learned from past efforts: What have we learned from past efforts: ARSET, GOES-R Air Quality Proving Ground, AQAST, DISCOVER-AQ About About What have we learned about the process of identifying needs and opportunities? Has that evolved over the course of the project/activity as the two communities have become more familiar with one another? What have we learned about effective ways to deliver data and tools? What have been the most "successful" projects in terms of producing something that the air quality community continues to use? Given the experience in this project, what user needs do we think that TEMPO and other aspects of GEO-CAPE should focus on? What processes (groups, workshops, ...) and procedures need to be in place to address those needs effectively?
