Sentences with phrase «limited by radiation»

ie does a slightly lower density of air mean a slightly lower ground level temperature (temperature normally decreases with height at the lower air density), so that in reality adding CO2 and subtracting more O2 actually causes miniscule or trivial global COOLING, and the (unused) ability of the changed atmosphere to absorb radiation energy and transmit it to the rest of the air is overruled or limited by the ideal gas law?

Radar measurements sum up the radiation over a beam whose apeture and sampling are settled (under ideal conditions) by the diffraction limit of the sensor.

The radiation to space is made less efficient by the existence of a warm stratosphere above the air, generating IR radiation from above, and limiting the net cooling of the upper troposphere.

Once the radiation limits begin to be increased this should have a catalytic effect on reducing emissions: 1) it will mean radiation leaks are understood to be less dangerous that currently thought > less people evacuated from effected zones > reduced cost accident of accidents — reduced accident insurance cost; 2) population takes another look at the effects of radiation > gains an understanding it is much less harmful than they thought > fear subsides > less opposition > easier and less expensive to find sites supported by the people nearby > planning and sight approval costs come down over time

36, to use your words, convection - limited would mean «It would be constrained by convective activity to keep in step with ground - level temperature, not by radiation.»

All types of solar geoengineering — known also as solar radiation management (SRM)-- are united by their goal of limiting the effect of sunlight on the Earth, but they vary widely in their approach.

CO2 molecules outnumber water molecules in the upper atmosphere, where water vapor is limited by the low saturation vapor pressure, and this is where radiation to space matters, so CO2 plays a big role in how much energy is radiated to space.

The scenarios include: «business as usual» (BAU), which assumes no mitigation efforts are made («RCP8.5»); «mitigation», which assumes an intermediate level of emissions («RCP4.5») without negative emissions; «carbon dioxide removal» («CDR»), which assumes moderate emissions with long - term CO2 removal; and «solar radiation management» («SRM»), which is the same as the CDR pathway, but also includes enough SRM to limit temperatures to 1.5 C above pre-industrial levels by 2100.

The lower sunlight means less radiation to be absorbed by co2, you can not make up for lower input because there is a limit on availability of radiation to absorb by co2.
