As the effects of global warming continue to create significant weather-related challenges, it has also negatively impacted the quality of ambient air in densely populated and/or urban areas. The most vulnerable populations (children/elderly) of these communities being the most at risk to adverse health effects (respiratory, cardiovascular). To get a better understand of the impact, a baseline for the ambient air quality is needed. Therefore, Harris County Pollution Control Services (HCPCS) has designed and built a mobile platform with the goal of monitoring the ambient air. The platform will serve a dual purpose and will measure the impact to air quality from specific emission events (natural/anthropogenic) and develop a baseline for ambient air quality in Harris County (Blue Skies Project). The Rapid Ambient Air Monitoring vehicle (RAAM) is equipped with an array of air monitoring equipment that utilize different techniques such as UV-VIS, Cavity Ring Down Spectrometry, PID, FTIR, and GC-MS to identify and quantify various toxicants. The RAAM is also equipped with a PM 2.5 monitor, meteorological station, and 5G wireless capability to report data in real-time. This data is collected and displayed on an interactive ArcGIS map. Utilizing these capabilities the RAAM will be able to construct an accurate portrait of the background ambient air quality in Harris County. Using that background data HCPCS will be able to determine the impact of emission events with more clarity and certainty.
