(meteorobs) "global dimming" and seeing?

[Steven Albers]

    Hi Fred,

    Commenting on this I'd say the scattering by haze does cut down on direct transmission of light, so the sun or stars would appear dimmer. I would gather that the total solar radiation reaching the ground (direct plus scattered) also is diminished.

    I think this idea has been around for quite a while in that I had thought this would help the eastern US have less warming than the western US. It's good to take a fresh look at it though. Since we are starting to clean the air from particulates then yes, warming would accelerate.

    I've updated once again my global warming discussion on my home page, with more about sea level and other items.

                                                   ...Steve

Anyone seen any research on implications of global dimming

)

and astronomy?

Is this just the light haze we've always been aware of or is it that  
plus an actual diminuition of the transparency of the atmosphere?
