Rarely here this time of year (weather 🤮) but I’m surprised by Ubon readings of 150 or higher, when generally the readings here are much lower than CM for example.
While there is no doubt a light haze around (I put that more down to the blistering temps and near dead still wind), there’s no noticeable smoke odour, and I don’t think Ubon is large or congested enough to have high 2.5 from industrial factors.
Going to Oz with the Mrs on Wednesday but like most here all I can say is….bring on the rain ☔️
