In 2015 the United States (US) Department of State launched an Air Quality Monitoring Program with the primary goals of protecting US personnel and their families, obtaining sound data to reduce exposure, evaluating the Department’s enterprise risk, advancing scientific understanding, and highlighting US technology and leadership. This effort has contributed air quality reporting at many embassies and consulates around the world. Volunteer on-site Air Quality Fellows provide the scientific expertise behind this program. Air Sciences’ Dr. Katheryn Kolesar recently returned from such a trip to Cairo, Egypt.
