Air Quality Information Updated 06/09/2023 10:00 a.m.
Air quality conditions in Tompkins County and surrounding areas have improved to normally acceptable levels with Air Quality Index (AQI) values below 100. Previous New York State Department of Conservation air quality advisories and alerts have been cancelled.
Information about the Air Quality Index (AQI) and current air quality conditions is available from AirNow.gov.
There are currently no air quality related restrictions to campus operations. Questions about workplace health and safety should be directed to Environment, Health and Safety through this askEHS form, by email to askehs@cornell.edu, or by calling 607-255-8200.
If wish to protect yourself from poor air quality from fine particles, high quality masks, such as N95 and KN95 masks, can be worn outdoors to reduce the inhalation of fine particles from the air. Cloth masks and surgical masks are not effective at reducing inhalation of pollutants. KN95 masks are available in the Cornell Police Department lobby in Barton Hall, at Cornell Health, in campus libraries, and at many Campus Life Community and Service Centers. Campus units can contact Facilities and Campus Services R5 Operations to obtain quantities of KN95 masks.
This is expected to be the final update related to the June 6 – 9, 2023 air quality issues.
