Anyone else noticed that the US embassy's PM 2.5 has been unchanged for the last while? I wonder if it has anything to do with the Beijing government's decision to report PM 2.5.
Perhaps they could permit the indirect and non-contradicting confrontation of the PM 10 vs PM 2.5, but won't accept direct comparison.
Anyone know anything? It sure seems a LOT worse than PM 2.5 94 today...
