So, just like any April in South Korea, with yellow dust alert...
Seriously, this is not the circumstances usually encountered in Vancouver, BC, which I remember as having beautiful clear skies.
I hope this is resolved quickly.
As for the resizing of photos, I use Fast Stone viewer.
I tried to edit your photo a bit, using autocontrast in Picasa, but the result was very weird - this smoke really destroys the chance of a good photo.
Stay safe.
Cheers
