Composition


NEMO is an ocean modeling platform composed of several models and numerical techniques for the use and processing of incoming and outgoing data. It has five main components:


  • Ocean: NEMO-OPA (Océan Parallélisé)

  • Sea ice: NEMO-LIM ("Louvain-la-neuve sea Ice Model")[1]

  • Biogeochemistry: NEMO-TOP/PISCES ("Tracer in the Ocean Paradigm")[2]

  • Grinding refinement tools: NEMO-AGRIF

  • Data assimilation system: NEMO-TAM ("Tangent linear and Adjoint Model")[3]

It can be associated with other components of the climatic system, atmosphere and land surface, by means of OASIS.



Grid


Nemo is available in various configurations.[4]


Global configurations use ORCA tripolar grids, which allow the entire oceanic domain to be covered without singularity points.[5] In fact, the grid formed by the meridians and the parallels has two singularities: the North Pole and the South Pole. Near these two points the mesh size tends to zero, making the use of modeling equations problematic. To overcome the problem, the poles of the ORCA grids are positioned on the terrestrial sphere in such a way as to be located on continents. Since the South Pole is located on the Antarctic continent, a modification of the standard grid is not required, while the North Pole, which is located in the Arctic Ocean, is replaced by two points located one in North America and the other in Siberia. The ORCA grid is available in different horizontal resolutions ranging from about 2 degrees to 1/12 degree.



Development


The development of NEMO is organized and controlled by a European consortium[6] created in 2008 and formed by:



  • French National Center for Scientific Research, France


  • Mercator Ocean, France


  • Natural Environment Research Council, United Kingdom


  • Met Office, United Kingdom


  • Euro-Mediterranean Center on Climate Change, Italy


  • National Institute of Geophysics and Volcanology, Italy

Displaying single band from multi-band raster using QGIS

Clash Royale CLAN TAG #URR8PPP 1 How can I extract a single band from multi-band raster in QGIS? I have an remote sensed image which has 6 bands (including NDVI band), I want to display each band separately, but have no idea how to do. I have seen some questions similar here but none worked for me. The original image (has 6 bands) is: I want to display the band 6 which should be like this: But I tried gdal_translate, and couldn't get the correct result.

How many registers does an x86_64 CPU actually have?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
