practical issues uncovered in the active source experiments.
It will double as a data report required by IRIS.
This probably should also include the weight drop experiment.
Publication options are a new AGU journal Earth and Space that encourages this kind of paper. Alternatively, Seismological Research Letters recently announced it will consider similar papers.
Boise/Caltech on surface active excitation
Determine what goes in which paper.
Similar paper on the 3D array
SRL might be more appropriate for this one as it has a higher impact factor, and is appropriate for papers without very deep science, more speculative things.
Show some data in this paper, such as the seismic noise levels, variation over time, variation with depth, maybe coherence plots. No significant data analysis, just basic things.
Parameter estimation for the Rayleigh and Love eigenfunctions (amplitude vs depth dependence).
This could be a separate paper, or a part of the above paper.
Include inversion (using velocity structure) and parameter estimation (probably)
Estimating directional and modal composition of the seismic noise.
This would include the radiometer method description, some simulations, and applications to real data IF we manage to convince ourselves that the method is working.
Try this first at low frequencies (0.1 Hz), maybe compare with other existing techniques. And then work upwards in frequency until things start to break.
For an estimate of the modal and directional composition of the seismic noise, compute the estimate of Newtonian gravity fluctuations. Could be done using (semi)analytical approach, or maybe purely numerical simulations.
Wiener filter application (Jan/Michael)
Ran the old wiener filtering code on the new data.
There are ideas about related analyses, eg estimating the body waves by filtering 4850 with surface stations. Time scale, not sure, depends on what new things we want to add.
