I’ve wondered about that.

Even in rural towns, the midday sun in India feels “dimmer” on a clear day. Even for the winter, this seems odd as the relatively lower latitude should make for more direct sun.

It feels like the soft warm filters used in photography… Outdoor sun normally bothers me greatly, but there sunglasses don’t even seem needed…

Not sure what proportion is coal dust, dirt, or wood smoke but something major is definitely going on…
