The standard AQI information is already available to the public through multiple sources so why do you need TrueAQi? Let us answer that. With TrueAQi you get real-time ambient air quality information and pollutant levels across India. We calculate the AQI based on hourly concentrations instead of a 24-hour aggregate. It has several advantages, especially in scenarios where real-time air quality monitoring is essential. Here are five key reasons:
- Immediate Public Awareness and Response
Hourly AQI values reflect real-time air quality conditions, enabling individuals and communities to respond quickly to changes. For example, if pollutant levels spike due to heavy traffic, people can take immediate precautions like staying indoors or using masks. Use Case: Alert systems for sensitive groups (e.g., asthma patients) can be more effective with real-time data.
- Better Decision-Making for Outdoor Activities
Many outdoor activities, such as exercise, commuting, or events, are influenced by short-term air quality fluctuations. Hourly AQI helps people plan their day more effectively compared to a 24-hour average, which might not capture sudden spikes or drops. Example: Schools can decide to cancel outdoor sports based on hourly AQI rather than waiting for a 24-hour average.
- Captures Pollution Events More Accurately
Short-term pollution events, like industrial emissions, construction activities, or fireworks, may not significantly affect the 24-hour average but can pose serious health risks during peak hours. Hourly AQI ensures these events are not “diluted” over a full day. Example: A factory releasing pollutants for a few hours may have little impact on the 24-hour AQI, but the hourly AQI will highlight the immediate risk.
- Dynamic Policy Enforcement
Hourly AQI enables real-time enforcement of pollution control measures. Authorities can take timely actions, such as restricting vehicle movement, shutting down industrial operations, or issuing public advisories, based on hourly trends. Example: A sudden rise in PM2.5 can trigger localized restrictions or interventions to mitigate pollution levels quickly.
- Improves Health Risk Assessment for Short-Term Exposure
Some pollutants, like ozone and nitrogen dioxide (NO₂), can cause adverse health effects within a few hours of exposure. Hourly AQI is more relevant for assessing risks associated with acute exposure, whereas 24-hour averages are more suited for chronic exposure assessments. Example: People with respiratory conditions can monitor real-time AQI to avoid peak pollution hours.
