“Rebecca Koh” writes on Channelnewsasia.com’s special haze page that:
The view from my office which is located at Gateway East along Beach Road was worse than yesterday or few hours earlier. But the PSI Index shows only slight difference.
Are the PSI index reported by the respective department in charge accurate?
It’d be great if someone could teach us how to assemble our own DIY PSI kit, wouldn’t it?
