Our technical staff and my students are currently using the methodology developed by Clean Air Asia and have covered several major thoroughfares in Metro Manila and a highly urbanized city in studies that have been undertaken in the last 6 years. I already asked them to take a look at the new tool and see how this compares with the ones we are using.
