Air Quality at US Embassies and Consulates

Last year, over one-fifth of all U.S. citizens spent significant time abroad. In the past, when U.S. citizens were overseas, they did not have ready access to air quality data. Today, thanks to a partnership between the U.S. Department of State and EPA, AirNow reaches beyond our borders to provide air quality data for Americans living and traveling abroad. This service begins with the installation and operation of state-of-the-art air quality monitors at U.S. embassies and consulates. Currently, 28 such monitors– made in the USA – operate at these facilities, providing hourly data to anyone who wants it. More are on the way: a total of 35 monitors are expected to be installed by fall 2018.

By bringing in high quality equipment, and by following data collection and reporting criteria used in the U.S., these embassies and consulates provide Americans overseas with air quality information that is based on the Air Quality Index (AQI) used in the U.S. (Several other countries and institutions have created their own air quality indices; U.S. embassies and consulates use the U.S. AQI, because it is based on U.S. air quality standards and supporting health information.) The rigorous monitoring and reporting approach the embassies and consulates use also serves as an objective model for foreign audiences, spurring local action to address air quality issues.

AirNow International: A Regional and International Collaboration Platform

In addition to providing air quality information for U.S. citizens, the AirNow program also helps other countries and regions share real-time information about the quality of their air.

AirNow-International (AirNow-I) is a platform for sharing and managing data. Its features -- like global mapping, multi-language capability, and adaptability to different time zones and air quality indices -- allow the system to be adapted for any city or country’s use. Starting with a pilot with Shanghai that was launched at the 2008 World Expo, today, a number of countries are using the AirNow-I to share data, and to use the data management and analytical tools the platform provides.
