This research project could influence aircraft operational procedures and aircraft/engine technology development that could exceed the $500 million per year threshold definition for highly influential scientific disseminations. The findings could also be controversial. A work product on contrails should be available to initiate the peer review process in FY 2009. The overall effort to reduce uncertainty in aviation’s contribution to climate change is a long-term effort, however, and other work products focusing on other emissions might be peer-reviewed in the future.
