Sentences with phrase «ir optical»

In the real (wet) atmosphere IR optical depth is dominated by water vapor.

I can accept IR optical depth has an effect on a system radiatively coupled to a heat sink at 2.725 K. I can also accept increased CO ₂ mixing ratio increases IR optical depth in a dry atmosphere.

I'm not propping him up but his paper did do one great thing, it measured the, how do I say it, average clear - sky Planck weighted IR optical thickness to a constant.

The answer that seems to fit that question is Miskolczi's GHG stabilisation model: total [H2O] falls to get constant IR optical depth corresponding to 1.87 average absorption events per photon emitted from the surface, a physical constant from the minimisation of free energy!

On the other hand it may turn out average IR optical depth is proportional to well mixed GHG concentrations with a specific constant of proportionality.

Of course, it may turn out average IR optical depth is in fact more stable than projected by computational models, so what?

and «So, if Miskolczi's IR optical depth of 1.87 is all - sky, then it is meaningless, if it is clear - sky, it is not known how the cloudless cases were sorted out of the whole.»

Re David L. Hagen December 27, 2013 at 6:49 pm at https://judithcurry.com/2013/12/20/open-thread-weekend-41/#comment-429721 You wrote re my question «What is the IR optical depth of the clear - sky part»: «Miskolczi is modeling the radiative absorption / radiation from ALL the greenhouse gas components of the atmosphere.

Therefore in water vapor absorption bands IR optical depth, as given by average water vapor concentration, only provides an upper bound to actual average IR optical depth, the latter being pretty independent of the former one otherwise.

But the the radiation emitted in space is again exactly the same, and so the «photosphere» (TOA defined by IR optical depth around one), what I understand being the «skin», is the same.

Not exact matches

As brown dwarfs are nearly invisible in the optical light and only emit radiation in the IR regime, they exhibit different colors in that range.

When compared to the total sample of LIRG CCSNe discovered in the near - IR and optical, we show that our method is singularly effective in uncovering CCSNe in nuclear regions and we conclude that the majority of CCSNe exploding in LIRGs are not detected as a result of dust obscuration and poor spatial resolution.

What's more, results from Keck's vortex coronagraph will help with a planet imager planned for the future Thirty Meter Telescope and with proposed NASA space missions, such as the Habitable Exoplanet Imaging Mission (HabEx) and the Large UV / Optical / IR Surveyor (LUVOIR), which would use next - generation vortex coronagraphs currently being designed in Mawet's group at Caltech.

Their optical and near - IR photometry, as well as their proper motion, are consistent with them being cluster members.

Using multi-epoch optical and near - IR follow - up spectroscopy with FLAMES on the Very Large Telescope and ISIS on the William Herschel Telescope we obtain a full orbital solution and derive the fundamental parameters of both stars by modelling the light curve and radial velocity data.

The scope and flexibility of SDSS - V will be unique among extant and future spectroscopic surveys: it is all - sky, with matched survey infrastructures in both hemispheres; it provides near - IR and optical multi-object fiber spectroscopy that is rapidly reconfigurable to serve high target densities, targets of opportunity, and time - domain monitoring; and it provides optical, ultra-wide-field integral field spectroscopy.

Zezas; Optical: NASA / ESA / CfA / A.Zezas; UV: NASA / JPL - Caltech / CfA / J.Huchra et al.; IR: NASA / JPL - Caltech / CfA

Can we simply resume the above article to a single line takeaway: Neonode's IR provides touchscreen functionality w / o needing any glass overlays (that reduce contrast and the optical quality)?

On top of those, they've each got two USB 3 ports, IR outputs, optical audio out, Ethernet ports and, of course, the power cable — which is compatible with both versions of the Xbox.

Along with the obligatory power port, the Xbox One S comes with a HDMI out and HDMI in, a brace of USB ports (with another on the front), an IR out, optical digital out and wired network port.

Kinect slots into the back of the Xbox One, next to a series of ports including HDMI - in, HDMI - out, three super-speed USB ports, an Ethernet connector, S / PDIF for optical audio out and an added IR port.

Around the back and One X comes with all the ports you would expect — HDMI in and out, an Optical output, an IR sensor, a couple more USB opportunities, an ethernet port and that all important power input.

From left to right you've got a power connector, HDMI out, HDMI in, two USB ports, an IR out, an Optical Audio port and an Ethernet port.

But to begin, note the physical chemistry of tri-atomic atmopspheric molecules; pass optical bands and absorb / emit IR.

However, less of that IR will escape, because of the increased optical thickness above it.

@RI: More CO2 raises the optical depth (in layman speak, the top of the GHG radiative «fog» above which IR is free to radiate to space and cool).

Again, the contention is that rising CO2 causes water vapor to rain out at such a rate as to make optical thickness of the atmosphere in the IR constant.

There seems to be no realization that his optical thickness is designed in such a way as to ignore the GHG effect, and has no relevance to IR emitted by the atmosphere where the GHG effect resides.

Miskolczi's optical thickness is how much of the surface emitted IR radiation reaches the top untouched and is equivalent to 15 %.

More CO2 raises the optical depth (in layman speak, the top of the GHG radiative «fog» above which IR is free to radiate to space and cool).
