Sentences with phrase «pan evaporation rate»

Anyway, a while back I saw a Nova / BBC special about the Global Dimming phenomenon (pan evaporation rate, etc.) that apparently had been discovered fairly recently, sometime in the late 90's I believe.

What surprised me was that such a significant effect was unrecognized in all the years that the pan evaporation rate had been measured, even though it has been affecting global temperatures.

Curiously, pan evaporation rates are steady or slightly down over land — something the models can not generally replicate.
