About this file

Written by GovTribe AI · Apr 30, 2025

This document is a November 2015 monthly report for the National Park Service Gaseous Pollutant Monitoring Program (GPMP), detailing environmental monitoring data collected across multiple national parks. The report provides comprehensive summaries of ozone, particulate matter (PM2.5), sulfur dioxide, and meteorological data from monitoring sites at various national parks including Big Bend, Canyonlands, Joshua Tree, Yellowstone, and others.

The data tables include key metrics such as highest daily maximum 8-hour average concentrations, wind speed, ambient temperature, relative humidity, and data collection statistics. Each monitoring site's performance is evaluated against national ambient air quality standards, with no sites exceeding the 8-hour ozone standard of 0.075 ppm during the reporting period. The report demonstrates robust data collection, with most sites achieving over 90% valid data capture across multiple environmental parameters, highlighting the thoroughness of the National Park Service's environmental monitoring efforts.

1. The primary and secondary National Ambient Air Quality Standard for ozone is 0.075 ppm over an 8-hour period. (Attainment of the primary standard is reached if the annual fourth highest daily maximum 8-hour ozone concentration, averaged over three years, does not exceed 0.075 ppm, 75 ppb, or 147 µg/m³.) (40 CFR 50.10 with reference to Appendix D and I.)

2. The primary and secondary National Ambient Air Quality Standard for ozone is 0.12 ppm over a 1-hour period not to be exceeded more than once per year. (A value greater than 0.12 ppm, 124 ppb, or 235 µg/m³.) (40 CFR 50.9 with reference to Appendix D and H.)

3. An exceedance of the National Ambient Air Quality Standard for ozone occurs when an 8-hour average ozone conentration exceeds 0.075 ppm, 75 ppb, or 147µg/m³. (40 CFR 50.10 with reference to Appendix D and I.)

1. Percent valid can be less than 100% due to calibrations, routine maintenance, power failures, audits or other circumstances where the instrument was not available to collect data.

For example, automatic zeros and spans are performed daily on most ambient gas analyzers; therefore, no ambient gas data can be collected during this time. As a result, the maximum percent valid for ambient gas data typically cannot be greater than 95.8. Percent valid can also be less than 100% due to influencing factors such as instrument error, operator error, timing problems, flow issues, and other factors that affect instrument operation.
