Sentences with phrase «radiation increases»

«From 1900 to 1998, solar radiation increased by 1.3 W / m ², but since 1998 it has diminished, and could reach values similar to those of the early 20th century.
Since the intensity of infrared radiation increases with increasing temperature, one can think of the Earth's temperature as being determined by the infrared flux needed to balance the absorbed solar flux.
Haigh's measurements showed that visible radiation increased between 2004 and 2007, when it was expected to decrease, and ultraviolet radiation dropped four times as much as predicted.
Although the idea that UV radiation increases without Earth's magnetic field is long - established, its effect on the evolution of life at this time should be limited, he says, as the radiation would not be able to reach and damage the germ line, the cells of the body used in sexual reproduction to pass genetic information to offspring.
Such UV radiation increases lead to an enhanced OH production, reducing the lifetime of CH4 and influencing tropospheric ozone, both important greenhouse gases (European Commission, 2003).
Laboratory experiments have shown that humans and other animals can adapt to radiation, and that prolonged exposure to low doses of radiation increases organisms» resistance to larger, subsequent doses.
In addition, strong biosphere - radiation feedbacks are often present in several moderately wet regions, for instance in the Eastern U.S. and in the Mediterranean, where precipitation and radiation increase vegetation growth.

In fact, the same radiative calculations performed by the ISCCP group show that the outgoing longwave radiation increases during this time, opposite to the effect claimed.
The National Academy of Sciences takes a stronger stance, concluding that any amount of ionizing radiation increases cancer risk, but radiation biologist Jacqueline Williams, who works at University of Rochester Medical Center, told the AP the risk is minimal:
Recent satellite data have revealed, however, that there seems to be a surprising spectral component to solar variability, at least in the declining phase of the current solar cycle: UV radiation decreases strongly while visible radiation increases.
Since the intensity of infrared radiation increases with increasing temperature, one can think of the Earth's temperature as being determined by the infrared flux needed to balance the absorbed solar flux.
In fact, a radiation increase MUST exist for the climate system to be stable, at least in the long term.
This solar radiation increases the temperature of the thermo - oil Heat Transfer Fluid (HTF) flowing through the receivers.
The combination of a cooler surface due to lack of solar radiation and a warmer boundary layer due to absorption of solar radiation increases the thermal stability and reduces cloud formation, and thus can reduce rainfall.
