Sentences with phrase «downward infrared radiation»

Surface measurements find more downward infrared radiation warming the planet's surface.

As far as water vapor in the tropics, they even say» In the humid equatorial regions, where there is so much water vapour in the air that the greenhouse effect is very large, adding a small additional amount of CO2 or water vapour has only a small direct impact on downward infrared radiation.»

Detailed studies of the energy balance and ablation of the Zongo and Chacaltaya glaciers support the importance of air temperature increase, and identify the increase in downward infrared radiation as the main way that the effect of the warmer air is communicated to the glacier surface [Wagnon et al. 1999; Francou et al, 2003].

So obviously there is a discrepancy which they cover by proposing that there is a flow of downward infrared radiation from the sky to ground (DWIR) of 33 units.

This increase in downward infrared radiation has been observed through spectroscopy, which measures changes in the electromagnetic spectrum.

2) If the sole determinants of surface temperature are mass, gravity and insolation then what role is played by upward infrared radiation from the surface (UWIR) and downward infrared radiation from the sky (DWIR)?

In fact, on average through day and night and over a whole year over the whole Earth's surface, downward infrared radiation is more important than downward solar radiation from the Sun in warming the surface.»

As reported by the IPCC in the Physical Science Basis, «In the humid equatorial regions, where there is so much water vapour in the air that the greenhouse effect is very large, adding a small additional amount of CO2 or water vapour has only a small direct impact on downward infrared radiation.
