Welcome to REM (Reference Earth Model) analysis website. I created the website while been sponsored by the CSEDI section of NSF.

The links on the left (under the "Reference Earth Model" section) will help you to investigate and analyze the inner structure of the Earth.

The data set consists of eleven recent models of seismic tomography. All of them are 3-dimensional and represent a relative anomaly of the seismic waves across the Earth mantle in percent.

Currently, there are five types of interactive analysis available to you here:

• Map view allows you to see a map view of a seismic anomaly at a choosen depth. It is also wrapped as a movie.
  
• Slice page allows you to see how the seismic anomaly changes with depth. Once you select two points of a Great circle, an additional window appears on your screen with the crossection along the Great circle.
  
• Isosurface page is where you can view a seismic anomaly isosurface in 3-D and all the way around from the different view points. Movie repeats the whole rotational sequence.
  
• rms page allows you some frequency analysis for the six longest wavelengths - the spherical harmonics l=1-6. Both, the depth profile and the colorful image are provided.
  
• Correlation page. Here you can compare models to each other by analyzing the cross-correlation between the two models of your choice at different depths.
  

The final, vis5D page gives a reference in case you would like to do a more thorough visual analysis.

Enjoy the show!
