Sentences with phrase «average effective temperature»

After launch, large thermal gradients due to solar heating developed within the hot load, making it difficult to determine from the thermistor readings the average effective temperature, or the temperature the radiometer sees.

Not exact matches

Our effective temperature scale is between 0 - 200 K cooler than that expected from the Infrared Flux Method, depending on the adopted extinction map, which provides evidence for a lower value on average than that inferred for the Kepler Input Catalog (KIC).

The standard assumption has been that, while heat is transferred rapidly into a relatively thin, well - mixed surface layer of the ocean (averaging about 70 m in depth), the transfer into the deeper waters is so slow that the atmospheric temperature reaches effective equilibrium with the mixed layer in a decade or so.

So after considering all of that, the estimated current «surface» temperature produces an estimated effective radiant return energy from the atmosphere of about 345Wm - 3 + / - 9 called DWLR which, had the average effective radiant energy of the oceans been used, ~ 334Wm - 2 would have created less confusion and still have been within a more realistic uncertainty range of + / - 17 Wm - 2.

The effective radiant layer of the atmosphere is roughly at an average altitude of 5000 meters and temperature of roughly -30 C degrees.

Without them the albedo would be low and the effective average temperature of the surface above 0C.

Each attempt to «improve» your estimate of the global average temperature for a given month, year, etc., will not converge to the correct value but just produce another random number within the random - number generator's effective range, no more and no less meaningful than the previous one.

On average, there won't be a change in the equilibrium radiating temperature of the Earth, but there will be a change in the effective radiating altitude consequent on the change in the atmosphere's effective thermal conductance.

Major fossil fuel companies have today released a Joint Collaborative Declaration under the Oil & Gas Climate Initiative (OGCI) recognising the need to limit global average temperature rise to 2 ⁰ C. Launched in Paris this morning, they are calling for an «effective climate change agreement at COP21».

In November, delegates to the UN Climate Change Convention annual negotiations will gather in Paris to try to conclude an ambitious and effective agreement on preventing the global average temperature rise caused by greenhouse gas emissions exceeding 2 ˚C above its pre-industrial level.

The Earth's atmosphere, satisfying the energy minimum principle, is configured to the most effective cooling of the planet with an equilibrium global average vertical temperature and moisture profile.

This is * not * the average value of the temperature T - that is why I called it an «effective radiative temperature», and not the «average temperature».

Now I did use the word «averages over the planetary surface», but these obviously weighted averages - the effective temperature is weighted by the fourth power of itself, and the effective emissivity is weighted by the forth power of local temperature.

The ratio of these gases allows for a much more effective and exact calculation of average global ocean temperature, according to Severinghaus and his team of researchers at Scripps.

This specific value of temperature and the lapse rate and altitude give the effective surface average temperature.

The effective average location of outgoing radiation is about 5 km, so the lapse rate times 5 km = -33 C. Note that the higher ground and thus air temperature near the ground then cause the higher radiation levels.

In the real world; that being the laboratory where CO2 does its dastardly deed on our climate, the source of the energy that purports to do the heating, is (on average) a black body like source of Long wave infrared radiation having a spectral peak at about 10.1 microns wavelength, and containing about 98 % of its energy in a range of about 5.0 to 80 microns wavelength, at an effective Temperature (on average) of 288 Kelvin.

The following profile shows the effective temperature that the SOI contributes to the global average temperature over the years: This is a classical compensation term.

All of the positive and negative feedbacks to the greenhouse effect give an average temperature of 288K, or effectively 390.7 watts / m ^ 2, for an effective magnification of 1.226

For the 120th time (okay, maybe it's only the 19th), the temperature at the earth's surface is determined by the lapse rate and the level in the atmosphere at which the temperature is constrained, which is the effective radiating level, i.e., the average level from which radiation can successfully escape to space.

Estimates of the Earth's average albedo vary in the range 0.3 — 0.4, resulting in different estimated effective temperatures.

The surface temperature is the effective radiative temperature -LRB--18 C) plus the average height of emission (5.5 km) times the (moist) adiabatic lapse rate (6 C / km).

If we assume that your 240 w / m2 is correct, we can use Stefan - Boltzman Law to calculate the «effective» black body temperature of the earth, which if you accept «average» as an argument, would occur not at earth surface, but somewhere between earth surface and the top of the atmosphere.

for instance, the average temperature can vary without varying the effective temperature, that is with the same energy budget — and conversely.

What it does do, however, is raise the effective radiating level in the atmosphere... i.e., the level at which the temperature has to average about 255 K.

When you double CO2, the average effective radiative temperature drops from about 255 K to about 254 K.

But the quietly forget that they are talking about +1 at the «effective black body» temp of the earth, which is -19 as opposed to the average surface temperature which is +15.
