I want blue sky...please


I've not posting in SkyWatch Friday since Sept 2015. Malaysia has been affected by severe haze due to forest fires in the region in this duration (from Sept to Oct). The air were polluted and we have to wear face mask. School was closed due to worsen API. Outdoor activity are limited. Standard Chartered KL Maraton 2015 which supposed to be held on Oct 5,2015 was cancelled due to worsen air quality in Kuala Lumpur. 


Notes to travelers 
The deterioration in the air quality and visibility conditions cause by haze. The hazy situation happened around August - October, dry season in Malaysia, Singapore, part of Thailand. The haze problem was caused by uncontrolled open burning to clear land agricultural uses (worsen if in dry season) in Indonesia. The prevailing southeasterly winds blowing in haze spreading westward from Sumantra and Kalimantan. The situation turning serious from year to year.

For the air quality measurement, Malaysia is based on API (Unhealthy Air Pollution Index). In addition to API, Singapore also measure air quality based on PSI which will revealed the 6 pollutants (sulphur dioxide (SO2), particulate matter (PM10) and fine particulate matter (PM2.5), nitrogen dioxide (NO2), carbon monoxide (CO) and ozone (O3).


  
The sky in the morning (Oct 16,2015) was good. Thanks to heavy rain poured down yesterday.

I like your photos and I read about the haze on another bloggers blog. However I didn't know what was causing the haze. Is it pollution?
