Sentences with phrase «sky emittance»

A low cloud cover increases the sky emittance and hence «back» radiation.The surface energy balance then shows that the surface temperature increases and the convection heat loss from the ocean decreases: thus the nighttime subsurface ocean temperature does not decrease as much compared to that for a clear sky.

In Figure 1, I use the NCAR radiation model, and don't make any assumption about the apparent sky emittance.
