San Francisco Airport Aircraft Noise Exceedances Since 2005

San Francisco International Airport monitors aircraft noise levels on the San Francisco Peninsula 24/7. Louder noise events exceeding defined thresholds at 29 specific monitor sites are recorded, with data available starting January 2005 and updated monthly. This dataset is correlated to SFO aircraft operations and serves as the source for exceedance figures in the Airport Director's Report.

Use Cases

• Analyze temporal patterns of noise exceedances based on the monthly updates and historical data starting from 2005.
• Compare noise levels across different monitor sites based on the 29 listed sites with varying daytime and nighttime thresholds.
• Correlate noise events with airport operations based on the description that events are linked to SFO departures and landings.
• Assess compliance with noise regulations based on the defined maximum level thresholds for each site.

Strengths

• Data covers a long historical period, starting January 2005.
• Monitoring network includes 29 distinct sites with specific thresholds.
• Update frequency is monthly, providing regular data refreshes.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data scope is limited to SFO aircraft operations, excluding other Bay Area airport activities.
