What is the analysis of the 'pollution' in the air? I don't think it has anything to do with 'burning' or cars, trucks and busses. Today in Bangkok, we had a 3 hour rain storm early in the morning - but the online weather forecast showed sunny conditions with zero chance of rain... What is going on? Look up and see the trails for an answer.
I flew domestically a couple of days ago - no sign of burning, BUT there was a layer of fug that the plane bounced over at about 15,000 feet. Why and what is going on? I've been in Thailand for 20 years, and silver skies were not normal for many of those years....
