Sentences with phrase «aogcm radiation codes»

A simple example is the radiation code — instead of using a line - by - line code which would resolve the absorption at over 10,000 individual wavelengths, a GCM generally uses a broad - band approximation (with 30 to 50 bands) which gives very close to the same results as a full calculation.

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.

What is done in radiation codes is APPROXIMATION, this is fairly different fron cloud parameterizations for instance since, in that case, there is some physics which is by - passed because the physics works at a smaller scale.

The accuracy of RRTMG is verified through comparison to AER's reference radiation code LBLRTM, which is directly validated with atmospheric measurements provided by high - quality spectral measurements from satellite -, aircraft - and ground - based instruments.

Line - by - line radiations codes do the full calculations for the actual absorption lines as they exist in the atmosphere in order to nail down the effects quantitatively.

There are still significant discrepancies between the AOGCM radiation codes and LBL codes in the models used for IPCC AR4.

Not exact matches

While CO2 laser radiation is unable to generate codes on uncoated beverage cans due to its reflection off metal surfaces, the latest fibre laser systems are perfectly suited for these type of applications: thanks to their high pulse peak power they can code bare aluminium, as well as coated or anodised aluminium, leaving an indelible mark by anodising the surface (a process that does not engrave but actually creates a protective layer on the aluminium).

It is the first DNA analyser to head into space, and may eventually allow astronauts to directly monitor changes to their genetic code caused by the harsh radiation environment in orbit.

Even with whole genomes, some of the earliest branches in Neoaves proved challenging to resolve, which was best explained by massive protein - coding sequence convergence and high levels of incomplete lineage sorting that occurred during a rapid radiation after the Cretaceous - Paleogene mass extinction event about 66 million years ago.

The researchers also used rods printed in a cross formation to create two separate QR codes that could each be read with a different polarization of terahertz radiation.

Nahata's team used terahertz radiation to read the coded information because the wavelengths in this region are best suited for imaging the resolution available from commercial inkjet printers.

To the naked eye the images look like an array of identical looking lines, but when viewed with terahertz radiation, the embedded QR code image becomes apparent.

That's what prompted the researchers to use a multi-scale, multi-physics approach, employing two different codes: ZEUS - MP, which has the radiation transport required to evaporate the halo, and CASTRO, which was developed at Berkeley Lab and has the adaptive mesh refinement needed to resolve the collision of the ejected metal with the halo.

Axel Huebl, who joined the team a year after Burau, has pushed the code to make optimal use of all of Titan's GPUs, winning him time on Titan through DOE's Innovative and Novel Computational Impact on Theory and Experiment (INCITE) program for his PhD research on laser - driven radiation therapy of cancer.

During this phase two aspects of the simulation were discussed: (i) the fundamentals of the Monte Carlo simulation of radiation transport and of the physics of imaging detectors; and (ii) the structure and practical operation of the Monte Carlo codes PENELOPE / penEasy and the MANTIS family of codes.

The ESR will participate in both time - resolved WAXS and diffraction studies at synchrotron radiation sources and X-ray free electron laser, be educated in the tools of X-ray scattering and X-ray diffraction analysis, and develop code for the interpretation of structural changes using both methods.

I developed and host a web interface to the modtran model of atmospheric infrared radiation, an early example of a line - by - line code which I downloaded and use to teach and as part of a textbook.

Breaking the supermassive black hole speed limit — Using computer codes for modeling the interaction of matter and radiation related to the Lab's stockpile stewardship mission, scientists simulated collapsing stars that resulted in supermassive black holes forming in less time than expected, cosmologically speaking — in the first billion years of the universe.

The selected doctoral candidate will use a state - of - the - art fully - kinetic and massively parallel particle - in - cell code, running on European network High - Performance Supercomputers, to simulate the electromagnetic radiation caused by magnetic reconnection.

The paucity of single nucleotide diversity among breeds is consistent with other studies (29 — 32) and stands in stark contrast to the abundance of coding repeat variation we found in these same genes known to be involved in the developmental processes under selection in the radiation in dog breed morphologies.

His 1989 Technical Report gives a lengthy description (including also the FORTRAN code) of his line - by - line HARTCODE model, which can credibly compute the spectrally resolved outgoing TOA radiation for a clear - sky atmosphere.

Well, as you can see from this thread, you might be OK with radiative transfer code, but plenty of others are confused about radiation and the conservation of energy, in general.

In the thread on Confidence in Radiative Transfer Models, we argued that line - by - line radiative transfer codes and the best band models can accurately simulate clear sky (no clouds, aerosols) infrared radiation fluxes at the surface provided that the vertical profiles of atmospheric temperature and trace gas concentrations are specified accurately.
