Aircraft Noise Climates
Listed in DataSF Open Data Portal
A. SUMMARY San Francisco International Airport (SFO) keeps track of aircraft noise levels in communities around the airport 24/7.
Description
Measured aircraft noise events are used in calculations to determine Aircraft Community Noise Equivalent Level (CNEL). This noise metric is used to assess and regulate aircraft noise exposure in residential communities surrounding the airport.
The annual Aircraft CNEL helps validate the 65‐decibel noise impact contour, an output of computer noise modeling. B. HOW THE DATASET IS CREATED This dataset consists of measured aircraft noise events at each of SFO’s 29 community noise monitoring sites. Also provided as part of this dataset is ANEEM Aircraft CNEL.

This aircraft climate is derived using ANEEM algorithms that can measure quieter aircraft noise levels below that of conventional threshold correlation methodology resulting in improved noise to aircraft correlations. C. UPDATE PROCESS Data is available starting in March 2017. Aircraft climates derived using ANEEM algorithms are available starting January 2023.
This dataset will be updated on a monthly basis. D. HOW TO USE THIS DATASET This information is used to produce the monthly Aircraft Noise Levels section on page 1 of the Airport Director’s Report. These reports are presented at the SFO Airport Community Roundtable Meetings and available online at flysfo.com/about/community-noise/noise-office/reports/airport-directors-report Please contact the Noise Abatement Office at NoiseAbatementOffice@flysfo.com for any questions regarding this data.
