South Coast Air Quality Management District’s (South Coast AQMD) Air Quality Sensor Performance Evaluation Center (AQ-SPEC) received a U.S. EPA Inflation Reduction Act grant to expand its pilot Sensor Library Program. The agency partnered with four areas in the region  — Pacoima, Pomona, Riverside, and Vista Hermosa Heights — to deploy air sensors and provide hyperlocal, real-time data to communities.

‍

The Challenge

These communities sought to strengthen local air monitoring by adding sensor data to identify air pollution patterns, protect residents during poor air quality events, and develop evidence-based Community Action Plans to reduce emissions and exposure.

‍

The Solution

South Coast AQMD's AQ-SPEC Sensor Library Program partnered with JustAir to create a dashboard that integrates data from multiple sensor types including federal regulatory monitors to provide communities  with high-quality data.  Sensors in Pacoima launched on the platform in October 2025, with additional deployments in Pomona, Riverside, and Vista Hermosa Heights rolling out next.

Platform Capabilities

Monitor-Agnostic Integration

• Unified dashboard for 5+ sensor manufacturers (Aeroqual, Kunak, QuantAQ, etc.) alongside federal monitors. 
• Residents and administrators can view all air quality data in one place. 

Real-Time Insights & Quality Assurance

• Continuous data completeness validation and threshold monitoring.
• Pollutant-specific corrections and automated QA/QC ensuring data accuracy across all devices.
• Automated network anomaly detection.

Community-Focused Design

• Easy to use public-facing dashboard promotes neighborhood awareness and engagement.
• Interactive data visualizations — including calendar views, cross-sensor comparisons, and downloadable datasets — make complex air quality data accessible and actionable.

‍Impact

The AQ-SPEC Sensor Library Program equips communities with the infrastructure to:

• Establish baseline air quality data and identify potential areas of community concern.
• Enable real-time community protection during poor air quality events.
