Air Quality at the United States Embassy in Cairo

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.

Navigating Cleaner Air Oregon (CAO)

To track emissions at the national level, the United States Environmental Protection Agency (EPA) requires Oregon (and other states) to conduct statewide inventories from all sources of air pollution. These data collected from across the country are used for making new rules and modeling air pollution.

A few years in the making, Cleaner Air Oregon (CAO) addresses this need and is already affecting many companies in the state. As of November 2018, all permitted facilities should have already submitted emissions inventories for their sources to the Oregon Department of Environmental Quality (DEQ).

AEREarth: Visualize AERMOD Files in Google Earth

Air Sciences’ staff recently developed a tool called AEREarth for users who would like to visualize AERMOD air dispersion model input data in Google Earth before running the actual model. The AEREarth tool takes AERMOD input data files (extension .inp, or .api if using Lakes) and translates them into Google Earth KML files. These files allow the user to see a three-dimensional (3D) rendering of all air pollutant emissions sources characterized in the input file. The tool also can accept AERMOD BPIP files (.ppp, .pip, or .bpi) into 3D buildings. This visualization tool allows users to evaluate whether a facility is correctly configured in AERMOD, and provides a useful QA/QC check of the model data prior to conducting a potentially time-consuming model run.
