The top row of images show each study region in 2005, which had abundant NOx in urban areas where human emissions are high, leading to systems where ozone formation was controlled by VOC amounts. As pollution controls were put into place on NOx emissions, by 2015, the systems in Europe, the United States, and East Asian urban areas became limited by NOx, meaning that further controls on NOx would help reduce ozone formation.

NASA Finds New Way to Track Ozone By Satellite

Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. But it not directly measurable from space, due to the abundance of ozone higher in the atmosphere, which masks the surface. Now, researchers have devised a way to use satellite measurements of the precursor gases that contribute to ozone formation to predict when and where ozone will form.

The Human and Financial Cost of Pollution

We need to ensure that our air, water and soil is free of poisons and to do that we need to take pollution control more seriously than we do today. Many industries have found that environmental regulation is compatible with long term production and profits.

The sprayer, Caroline Obinju Ocholla, is 33 yrs old, married with 4 children - 5,8,10, and 12 years old. She currently volunteers as a CHV. She is doing this work to help the community but also to save money to help her family. She is motivated by the wages being paid for the work, the respect she recieves from the community (they trust her), her daughters and her spouse who is happy she is bringing in income and supports her. She also says community members prefer female sprayers. Some call her and specifically ask for her to spray their houses. In the future she hopes to be a hairdresser.
