AQI (Air Quality Index) is a standardized measurement of air pollution on a scale from 0 to 500. It’s calculated using pollutant concentrations like PM2.5, PM10, and ozone and adjusted through a formula that accounts for recent trends in pollution levels. 

AQI is calculated using pollutant concentrations of PM2.5, PM10, and ozone and is adjusted using a weighted AQI calculator like NowCast, which gives more importance to recent pollution spikes.

Perry Weather uses real-time air quality monitoring with NowCast, which weighs recent readings more heavily to provide accurate, up-to-the-minute data.

Perry Weather’s air quality monitoring platform tracks:

• PM2.5 – Fine particulate matter from wildfires, vehicle emissions, and industrial pollution that can enter the lungs and bloodstream and cause serious health risks.
• PM10 – Larger, coarse particulate matter from dust, construction, and roadways, which can cause respiratory irritation.
• Ozone (O₃) – A harmful gas formed when pollutants react with sunlight, causing lung inflammation and worsening asthma.

Perry Weather’s sensors measure PM2.5 and PM10 on-site, while Ozone data is provided via OpenAQ for expanded air quality coverage.

Perry Weather’s AQI sensors now measure both PM2.5 and PM10 using optical laser technology, which:

• Instantly detects pollution spikes, unlike slower filter-based sensors.
• Requires less maintenance, reducing downtime.
• Provides hyper-local AQI readings, so organizations know exactly what’s in the air at their location.

Most free AQI apps use city-wide sensor data, which can be:

• Miles away from your actual location
• Hours old, not real-time
• Generalized, not specific to your site

Perry Weather’s air quality monitoring system delivers:

• Real-time, site-specific AQI tracking with precise sensor readings.
• Automated AQI notifications when pollution levels rise.
• Reliable air quality monitoring equipment.

Perry Weather’s on-site AQI sensors give organizations precise, real-time readings for their exact location, eliminating guesswork when making safety decisions.

Yes! Perry Weather’s AQI monitoring can be:

• Integrated into emergency action plans for schools, sports teams, and construction sites.
• Used to trigger mass notifications for staff, students, and workers when air quality declines.
• Set to automatically adjust outdoor work & activity schedules based on real-time data.

Perry Weather ensures organizations react proactively instead of relying on outdated forecasts.

Perry Weather’s custom policy integration and automated AQI alerts allow schools to set custom thresholds based on their state or district’s AQI policies, automatically notifying coaches and staff when the AQI exceeds safe limits.

Perry Weather helps schools to:

• Set custom AQI thresholds for PM2.5, PM10, and ozone.
• Receive real-time notifications when air quality exceeds safe levels.
• Make data-driven decisions instead of relying on outdated city-wide reports.

Monitoring AQI is just the first step. To actively improve air quality, facilities should:

• Upgrade HVAC systems with high-efficiency air filters to trap pollutants.
• Reduce indoor pollution sources like industrial-strength cleaning chemicals and dust buildup.
• Use strategic landscaping to create buffer zones from traffic pollution.

Perry Weather helps schools and businesses track real-time AQI, making it easier to know.
