The evolvement of ULVZ at LLSVP margins--reference model with B=3.0 and etaC=1.0

<p>This tar.gz file is created and uploaded for the submission of the manuscript&nbsp;titled &#39;<em>The evolvement of dense ULVZs at LLSVP margins and implications</em>&#39; to the journal <em>Geophysical Research Letters</em>.</p> <p>This tar.gz file is for the reference model in the manuscript, which employs a buoyancy number B=3.0 and a compositional viscosity eta_C=1.0 for the ULVZ. The collection includes the raw output data and post-processed data illustrated in Figures 1 and 2.&nbsp;</p> <p>1. the /scratch directory</p> <p>This directory contains the raw output data of an numerical experiment calculated by CitcomS (modified from the CitcomS-3.3.1 version) for the evolvement of a ULVZ initially beneath a mantle downwelling. All data follow the CitcomS output convention. Files named *coord* are for the coordinate, *.buoy* are for the density anomaly, *comp_nd* are for the compositional fields (LLSVP and ULVZ), *temp* are for the temperature and velocity fields, *visc* are for the viscosity field. The time frame 12000 is the initial condition of this calculation with one stable LLSVP, having already evolved for ~2 Gyrs, at the bottom center of the model domain, as well as a newly emplaced ULVZ near one sidewall beneath a cold downwelling. The calculation is done for 10000 time steps till the time frame of 20000.&nbsp;</p> <p>2. the data_plots/ directory</p> <p>In Fig1/ directory: data for the illustration of Figure 1, the model initial condition.</p> <p>temperature: ULVZ-v1B3_h10l10.a.temp.12000.dat</p> <p>composition: ULVZ-v1B3_h10l10.a.comp.12000.dat</p> <p>velocity: ULVZ-v1B3_h10l10.a.velo_Sv.12000.dat</p> <p>density anomaly: ULVZ-v1B3_h10l10.a.density.12000.dat</p> <p>topography: ULVZ-v1B3_h10l10.a.botm.12000.dat</p> <p>In Fig2/ directory: data for the illustration of Figure 2, the evolvement of ULVZ at the LLSVP margin, including the *botm*, *density*, *velo_Sv*, *botm*, *postp.tracers-plume* for selected time frames.&nbsp;</p> <p>296 Myrs: time frame 14000</p> <p>519 Myrs: time frame 14800</p> <p>888 Myrs: time frame 16800</p> <p>1036 Myrs: time frame 17600</p> <p>1332 Myrs: time frame 19200</p>
