Bangkok Air Pollution

[edwardandtubs 1,522]

Seems like the OP and others in this thread are newbies. Pollution is no worse this year than it has been in previous years. The only difference is that monitoring of pollution has improved. A few years ago most monitoring stations only measured pm10 but now there are more measuring pm2.5 as well.

Here is a link to actual PM2.5 data for 2014, 2015, 2016: 

https://greenpeace.or.th/s/right-to-clean-air/PM2.5CityRankingsREV.pdf

 

Unable to determine if their data source differs from other data sources such as:

https://air.plumelabs.com/en/

 

But if they are using the same monitoring station data...

Then the average PM2.5 in 2017 when compared to 2016 increased by about 30%

And this months (Jan 2018) average increased about 40% more then the max average in 2016

You seem to be getting confused between the index number and the micrograms per cubic metre number. I see no evidence in the websites you post that pm2.5 measured in micrograms per cubic metre has increased this year or last year.

Sorry, I should have been more clear... they refer to "PARTICULATE MATTER". It is not clear if this is PM2.5, PM10 or a combination. It is also not clear what unit of measurement they use. It is also not clear if they use the same monitoring stations. Assuming all of these are the same, then the numbers look much worse for 2017. Too many assumptions. 

 

Instead, I just found this, which proves your original point is true  the air is indeed equally bad in 2017 as it was in 2016, 2015 and 2014: http://www.nationmultimedia.com/detail/national/30323241

Don't worry, a lot of people get confused between the micrograms per cubic metre figures and the air quality index figures. Plumelabs seem to have created their own index.

 

Historical data is available from the following Thai government website:

Only a few of the monitoring stations have pm2.5 data. Din Daeng has had it for years though and the figures are quite consistent from one year to the next. Bangkok isn't all that bad compared to some cities. It's certainly a lot better than Beijing or Shanghai.

It seems this is where the data on http://aqicn.org/ comes from. 

 

I am unable to set the historical filter to a date before 2018, does it work for you?

In the screenshot the Loei station was selected, but was the same reading as the bangkok marker at the time.

So a bit of fake news then.

Loads of thai drive to the mall to pay their telephone bill, is that thailand 4.0? It causes a lot of traffic which isn't necessary.

 

Also loads of thai drive to the bank because digital payments are not free, is that thailand 4.0?

I guess they even don't have automatic monthly payments at all.

 

It's time for Thailand to learn how usefull internet can be, they only use it for fayboo.

Troll much?

 

You can clearly see that the Bangkok station has the same reading as Loei.

 

If you prefer a screen shot with the actual Bangkok station selected, taken on the same day, here you go.

Its not just the fact that measuring might be more precise.  This air is the worst I've ever seen here, which is borne out by the numbers.

It isn't borne out by the numbers.  We've had a few unhealthy days because of weather conditions and this happens every year. It's as bad as ever  but what numbers show that it's getting worse?

I stay in Jomtien to avoid the pollution in pattaya (some hope) I like to do an early morning walk, after my walk on Monday I felt rough and was knackered till after a rain shower on Wednesday afternoon,only later did I read in the Bangkok post the advice was not to exercise outdoors.It was a bit foggy the visibility out to sea was poor and some fog inland,fog and no wind and pollution equal smog and I guess that's what took the wind out of my sails,I am 67 stopped smoking at 40 and just have a beer with my evening meal.

How does it feel? Might be more important than statistics.
