Sentences with phrase «atmosphere radiation measurement»

Scientists from these agencies will undertake programs in climate modelling, atmosphere radiation measurement, atmospheric science, the terrestrial carbon cycle, the ocean carbon cycle, and ecosystem research program, and finally will produce an integrated assessment, according to Dr. Raymond Orbach, the Energy Department's director of the Office of Science.

For instance, taking one of the two examples mentioned above, the radiation code can be tested against field measurements at specific times and places where the composition of the atmosphere is known alongside a line - by - line code.

The work is an estimate of the global average based on a single - column, time - average model of the atmosphere and surface (with some approximations — e.g. the surface is not truly a perfect blackbody in the LW (long - wave) portion of the spectrum (the wavelengths dominated by terrestrial / atmospheric emission, as opposed to SW radiation, dominated by solar radiation), but it can give you a pretty good idea of things (fig 1 shows a spectrum of radiation to space); there is also some comparison to actual measurements.

Are there any measurements made by satellites giving a time based record that shows variation in outgoing longwave radiation dependent on the amount of CO2 in the atmosphere?

Recent accurate laboratory measurements of the absorption in the CO2 band by CLOUD (1952) were used to calculate the radiation flux in the atmosphere with the aid of the MIDAC high speed digital computor.»

CO2 traps heat According to radiative physics and decades of laboratory measurements, increased CO2 in the atmosphere is expected / predicted to absorb more infrared radiation as it escapes back out to space.

In addition the measurement is non-trivial, because as Mosh has tirelessly pointed out, the act of spectroscopically measuring thermal radiation is dependent on a model of the radiative properties of the atmosphere.

Both measurements and models show that there is no reduction in IR radiation out at Top - of - atmosphere.

Whereabouts are those early 1950s precision measurements to be found which demonstrate that adding more carbon dioxide really would change how the atmosphere absorbed radiation?

The 324W / m ^ 2 of back radiation is overstated because the wrong emissivity value of the atmosphere has been used in calculating that back radiation from measurements.

Part Six — Visualization — where you can see the model results of downward longwave radiation in a known temperature / humidity profile through the atmosphere compared with the actual measurements of downward longwave radiation.

But for those who want to see a better experiment that compared real and modeled conditions, take a look at Part Six — Visualization where actual measurements of humidity and temperature through the atmosphere were taken, the detailed spectra of downwards longwave radiation was measured and the model and measured values were compared.

Abstract Measurements of the flux of downward solar radiation through the atmosphere of Venus and at the planetary surface are reported.

The evidence here comes from satellite measurements of infrared radiation escaping from the earth into outer space, from measurements of sunlight reflected from clouds and from measurements of the temperature the earth's surface or of the troposphere, the roughly 10 km thick layer of the atmosphere above the earth's surface that is filled with churning air and clouds, heated from below at the earth's surface, and cooled at the top by radiation into space.

When partnered with cloud remote sensing observations the radiation measurements and retrievals allow the characterization of cloud and aerosol radiative effects at the surface, which is essential in order to quantify the amount of radiative energy available at the surface to interact with heating the air, evaporating water, and interacting with clouds and greenhouse gasses in the atmosphere.

After all, according to scientific measurements the bulk of the Atmosphere, which is transparent to IR radiation, is made up from; Nitrogen (78 %), Oxygen (21 %) and Argon (0.9 %) and the rest = 0.1 % is made up from «trace gases» of which some are said to be «GHGs».

The problem is that you think it is a measurement of a ghostly «downward» radiation, while the authors of the graph are showing the spectral bands of several constituents of the atmosphere, not any measurement of any downward radiation.

1950s: Research on military applications of radar and infrared radiation promotes advances in radiative transfer theory and measurements = > Radiation math — Studies conducted largely for military applications give accurate values of infrared absorption by gases = > CO2 greenhouse — Nuclear physicists and chemists develop Carbon - 14 analysis, useful for dating ancient climate changes = > Carbon dates, for detecting carbon from fossil fuels in the atmosphere, and for measuring the rate of ocean turnover = > CO2 greenhouse — Development of digital computers affects many fields including the calculation of radiation transfer in the atmosphere = > Radiation math, and makes it possible to model weather processes = > Models (GCMs)-- Geological studies of polar wandering help provoke Ewing - Donn model of ice ages = > Simple models — Improvements in infrared instrumentation (mainly for industrial processes) allow very precise measurements of atmospheric CO2 = > CO2 greenhouse.

So, the 729.9 W / m ^ 2 shown during the hours just before and after noon on a dry clear - sky day should be reading somewhat below 729.9 / (1 — 0.313) or less than 1062 W / m ^ 2 by measurement, near noon, on the equator, for the atmosphere itself, in those conditions, would not be absorbing as much direct solar radiation as the average shows in column C either (no clouds).
