The Maricopa County Air Quality Department expects within the next two months to upgrade its air monitors in a move that will help officials report urban dust levels more quickly.
The goal is to use near real-time data to help prevent local violations of federal air-pollution limits.
The Arizona Republic reports that 24 monitoring sites across the Phoenix metro area now collect air-pollution levels every hour. But it takes extra time to store and distribute that information.
The upgraded monitors will collect data much quicker.
County officials hope to narrow down where the pollution is coming from and prevent dust levels from getting higher by making appropriate notification to businesses in those areas.
