Why sky is so bright and RED at night in south korea even there is no moon?

Question

I am a Bangladeshi now studying in south korea. The thing which is surprizing me is here at korea the night sky is totally different than in my country (may be it's seen only during this time of the year- I don't know). The night sky (usually I see it at 12.30/1.00am when I return to my home on foot from my lab) is so bright and there is always a reddish tone in that brightness even though there is no moon. I also cant remember to see any star in the sky

waiting for a logical answer or any link regarding this

:)

Answer 1

The only thing I can think of is that there is probably a lot of moisture and other aerosols in the air (dust, pollution, etc) that is reflecting and scattering the redder portion of lights from the city.  I always noticed this hazy condition when air moisture was relatively high.

Answer 2

It happens mostly in humid weather, but sometimes it happened in cold weather too. It has to do with the amount of pollution that S. Korea has... it gets into the air and messes around with the colors.

Answer 3

there could be ash in the atmosphere from volcanos. there are alot erupting currently, and they don't really have to be local to affect you. or maybe it's smog and the city lights are reflecting off of it.
