From the mannual, I knew the meaning of the columns in the ascii geoid file. There are eight columns in the geoid file, including columns of spherical harmonic degrees(l),order(m), cosine term of total geoid(Slm), sine term of total geoid(Clm), cosine term duing to surface topo,sine term duing to surface topo, cosine term duing to internal density variation and sine term duing to internal density variation. But, I found that there weren't cosine and sine terms for the CMB topo. Could anyone explain this to me, please? Thanks a lot.

If you need CMB topography in terms of spherical harmonics, you may need to modify the code yourself.

I want to make out whether the third and fourth columns in the geoid output file, which mean cosine and sine coefs of total geoid respectively, include the contribution of CMB topography. Also, I want to ask that if the density anomaly models, such as those transformed from seismic tomography could be inputted to the CitcomS, and how to do that? Thanks.

Participants will have access to FDSN data centers and HPC resources through the Livermore Open Campus (LVOC) to obtain and process seismic waveform data, run 3-D simulations to simulate the seismic wavefield in realistic 3D Earth models, and visualize the results. Tutorials will be offered in ObsPy, SW4, SPECFEM3D, and more! The workshop will include keynote talks on computational seismology, leading edge research, and tutorials. Software tutorials will include independent exercises and time for participants to tinker with their own research problems. Participants will share their research through posters and lighting talks to encourage scientific exchange. This workshop is close to capacity Deadline to apply is May 26. ALL foreign nationals must apply by this date. 15th International Workshop on Modeling of Mantle and Lithosphere Dynamics - NetherMod https://geodynamics.org/cig/events/calendar/nethermod/?eID=1314 Travel support is available for early career U.S. scientists.
