Last week we discussed how reduced nitrogen oxides (NOx) and better weather has improved Houston’s air quality dramatically over the past decade, especially with regard to ozone. Volatile organic compounds (VOCs) also react with sunlight to form ozone. Similar to the 54% reduction in NOx, VOC trends show a 65% decrease.[Read More]
Remember the historic heat and drought in 2011? We also saw ozone levels trend up slightly. Scientists and policy makers want to know whether ozone levels are going down because of weather patterns or because we are reducing emissions of the building blocks of ozone, nitrogen oxides (or NOx) and volatile organic compounds (or VOCs). This week we’ll look at trends in NOx.[Read More]
We know that Houston’s air quality has improved dramatically over the past 15 years. The Texas Commission on Environmental Quality (TCEQ) has a network of over 40 monitors situated all over Houston and the surrounding area—it’s the most dense air pollution monitoring network in the nation. Their data shows us that Houston’s air quality is much improved.[Read More]
