- abstract: The county-level daily PM2.5 dataset is created using data downloaded from the US Environmental Protection Agency (EPA) (https://aqs.epa.gov/aqsweb/airdata/download_files.html). These data were originally provided to EPA by the state of New Mexico Air Quality Bureau, as required under the Clean Air Act. Data are only provided for counties with monitors that pass the completeness criterion and those monitors that use a federal reference method (FRM) to monitor PM2.5. Most PM2.5 monitors take samples every third day (some every sixth day) and a few measure every day; taking quarterly averages and then calculating an annual average addresses the comparability of these data. The air quality PM2.5 data used in calculating the indicator are tested for completeness to ensure that there are 11 samples per quarter and 4 quarters per year for each area's year. If data for a county do not meet this completeness test, then they are designated as having "Insufficient Data" and estimates should be interpreted with caution. For counties without monitors, missing values are designated as "No Monitor." Effective December 17, 2006, the 24-hour National Ambient Air Quality Standard (NAAQS) is 35 mcg/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 mcg/m3. The dataset contains, for each county with complete monitoring data: the year, county FIPS code, and daily maximum ambient PM2.5 concentration (mcg/m3). The dataset was created using guidelines provided in the CDC NCDM Recommendations. 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 PM2.5-related air quality across NM by county with FRM PM2.5 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 PM2.5 monitors. As a result, the data tend to reflect urban air quality and longer-term average air quality levels. Populations in counties without FRM monitors may also be exposed to concentrations that exceed the standard. The annual PM2.5 level data help summarize long-term trends in particulate matter concentrations. These data will give an idea of what the annual level of PM2.5 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 year and over time (trends). The indicator measure (annual average concentration of PM2.5) can be compared to the NAAQS level of 35 mcg/m3 or other health-based benchmarks to communicate the degree of public health concern to policy makers and the general public. The measure can be affected by density and placement of monitors, and coverage will vary within the state. It does not directly reflect exposure. Certain geographic areas, such as those near busy roads, are likely to have higher values of PM2.5 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 PM2.5 measurements must always be considered when attempting to estimate the proportion of population at risk.

If data for a county do not achieve this completeness test, then the estimate should be interpreted with caution.
