If you actually look at the map data the difference between New York and 99% of India is only 3 vs 5 parts per billion. I could only believe in trash burning being the reason to that if and only if the difference would have been orders of magnitude. That difference could be easily accounted for only by the near presence of the mountains and thus lesser natural ventilation of the particles.
