NCore Multipollutant Monitoring Network

NCore is a multi pollutant network that integrates several advanced measurement systems for particles, pollutant gases and meteorology. EPA is coordinating with its state, local and Tribal partners, who will operate the NCore sites, on a list of possible site locations. The following web pages contain information and pictures of monitoring stations included in the NCore network discussions. The EPA welcomes input on the appropriateness of these candidate sites. For more information you may look at the strategy reference documents.

Monitoring Objectives

The NCore Network addresses the following objectives:

• Timely reporting of data to public by supporting AIRNow, air quality forecasting, and other public reporting mechanisms;
• Support for development of emission strategies through air quality model evaluation and other observational methods;
• Accountability of emission strategy progress through tracking long-term trends of criteria and non-criteria pollutants and their precursors;
• Support for long-term health assessments that contribute to ongoing reviews of the NAAQS;
• Compliance through establishing nonattainment/attainment areas through comparison with the NAAQS;
• Support to scientific studies ranging across technological, health, and atmospheric process disciplines; and
• Support to ecosystem assessments recognizing that national air quality networks benefit ecosystem assessments and, in turn, benefit from data specifically designed to address ecosystem analyses.
