        • abstract: The county-level daily NO2 dataset is created using data downloaded from the US Environmental Protection Agency (EPA) (http://aqsdr1.epa.gov/aqsweb/aqstmp/airdata/download_files.html). These data were originally provided to EPA by the state of New Mexico Air Quality Program, as required under the Clean Air Act. Data are only provided for counties with FRM (method code 8801) monitors that have annual monitoring. Most NO2 monitors take samples every third day (some every sixth day) and a few measure every day; summing the total number of days for each county above the National Ambient Air Quality Standard (NAAQS) standard and dividing by the total number of days monitored effectively provides an estimate of the percentage of days above the NAAQS standard for a given year for each county with FRM monitoring. Effective December 17, 2006, the 24-hour NAAQS for NO2 is 35 micrograms per cubic meter of air (ug/m3); to attain this standard, the 3-year average of the 98th percentile of 24-hour concentrations at each population-oriented monitor within an area must not exceed 35 ug/m3. For counties without FRM monitors, missing values are designated as "Data Not Available". The dataset contains, for each county with complete monitoring data: the year, state and county FIPS code (individually and combined), and percent of days with NO2 above the NAAQS. The dataset was created using guidelines provided in the CDC NCDM Recommendations (version 3.0). The indicator documentation is available from CDC's Environmental Public Health Tracking Network.
        • purpose: This dataset contains calculated measures for air quality for use on the NM public portal. The dataset is intended for use on the NM EPHT portal for displays describing NO2-related air quality across NM by county with NO2 FRM monitors. These data are not intended for performing health assessments or otherwise being directly related or linked to health data. The data for this indicator represent highly populated counties that have NO2 FRM monitors. As a result, the data tend to reflect urban air quality and longer-term average air quality levels. Populations in counties without monitors may also be exposed to concentrations that exceed a standard. The daily NO2 level data help summarize exceedance of short-term trends in fine particulate matter concentrations within and between counties. These data will give an idea of what the yearly exceedance of daily NO2 is in an area. This indicator can be used to inform policy makers and the public about the degree of potential exposures to fine particles within New Mexico during a given year and over time (trends). The measure (annual percentage of days above the NO2 NAAQS) can be compared to health-based benchmarks to communicate the degree of public health concern to policy makers and the general public. The measure can be affected by monitor density, placement of monitors, and frequency of monitoring, and spatial and temporal coverage will vary within the state. However, this measure does not directly reflect exposure. Certain geographic areas, such as those near busy roads, are likely to have higher values of NO2 levels. It is also important to understand that the relationship between ambient concentrations and personal exposure is uncertain, and it varies depending upon pollutant, activity patterns, and locality or microenvironments. The percentage of state population living in counties with no NO2 measurements must always be considered when attempting to estimate the proportion of population at risk.

      • complete: The air quality data used in calculating the indicator and measure are tested for completeness to ensure annual monitoring such that there sampling within the four (4) quarters for each area's year. If data for a county do not achieve this completeness test, then no NO2 estimate is made for the county.
