Sentences with word «longwave»

Calculation of solar irradiance i.e. shortwave radiation flux and the atmosphere's heat radiation i.e. longwave radiation flux is important.

Anthropogenic global warming is caused by an increase in the amount of downward longwave infrared radiation coming from greenhouse gases in the atmosphere.

Interestingly, the near - global observations show a greater drop in outgoing longwave radiation at the CO2 wavelengths around 700 cm - 1 compared to the change over tropical regions.

These results suggest that up to 35 % of the range in longwave forcing in the ensemble for the period 2080 to 2099 is due to the spread in forcing estimates for the specified increase in CO2.

As a greenhouse gas, this increase in atmospheric CO2 increases the amount of downward longwave radiation from the atmosphere, including towards the Earth's surface.

You say that the GHGs mean that the atmosphere is essentially opaque to outgoing longwave IR.

The following post at RealClimate on the effects of Downward Longwave Radiation on the oceans always stuck me as odd, but I can't put my finger on why:»

This is the science fraud so they can pretend that any downwelling measured from the atmosphere comes from «backradiation», when they are actually including the direct longwave infrared heat from the Sun.

4) Miskolczi's equation (4) setting downward atmospheric IR emission equal to the absorbed longwave flux from the ground implies that the atmosphere can somehow tell which heat comes from infrared and which comes from conduction, convection, or evapotranspiration.

The cooling impact of this AMOC forced surface heat flux perturbation difference is enhanced by shortwave feedback and diminished by longwave feedback and atmospheric heat transport differences.

The black line is the outgoing longwave spectrum in 1970.

And just as a semi-technical note on the above comment - strictly speaking the transmittance of the atmosphere doesn't need to be very low across the entire longwave band for the atmosphere to emit from the bottom meter.

It also means less longwave radiation escaping to space.

Part of this sensitivity is attributed to a physically realistic positive radiative feedback, whereby a propensity toward higher cloud fractions in any given simulation is amplified by longwave radiative cooling.

«A new absolute reference for atmospheric longwave irradiance measurements with traceability to SI units.»

Carbon dioxide, as well as CH4 and other gases, absorb and re-emit longwave radiation back to the earth's surface that would otherwise radiate rapidly into outer space, thus warming the Earth.

However, clouds also trap longwave radiation emitted by the Earth, as does water vapor.
