This README accompanies the data from wave propagation simulations through model 
supergranule cell. For details, see:

Dombroski, Birch, Braun, Hanasoge, 2011, Sol. Phys., in review.



FOLDER CONTENTS:

+ Simulation results are in the "data" folder 
+ Flow components of the model supergranule cell are in the "model" folder
+ Vertical (z [Mm]) grid is provided as the first column in the file "grid_xyz"



VERTICAL GRID SPACING:

The file "grid_xyz" contains the vertical (z) grid in the 1st column of that file.  
Dimensions are in Mm relative to the photosphere (z=0).  The vertical grid spacing
is nonuniform in cartesian space as it is designed to be roughly uniform in acoustic
travel time between grid points. 



HORIZONTAL SPACING:

Horizontal spacing is uniform (dx = 1/3 Mm) and equal in both the x and y 
directions.  



SUPERGRANULE MODEL:

Each V#0.fits file contains a 300^3 array defining a component of velocity at each 
point in a cartesian {x,y,z} coordinate system.  Velocity units are
in cm/s.



SIMULATION DATA:

Each file in the "data" folder contains a 300x300x1441 array containing the simulated 
observations for the respective physical case. These observations are a recording of the
fluctuating $v_z$ velocity at 200 km above the photosphere produced my simulating wave 
propagation through the supergranule model. The first two dimensions (300x300) 
correspond to the horizontal {x,y} domain, and the third dimension is a time index.  The
simulation was run for 24 hours of solar time, and observations were recorded at 60 
second invtervals.  The first index of 1441 is the initial state.  Velocity units are in 
cm/s.

"reference_vz_xyt.fits"
data from a reference simulation through the quiet sun stabilized background model S 
without the supergranule model. This simulation was conducted at the lower horizontal 
resolution.

"supergranule_vz_xyt.fits"
data from a simulation of wave propagation through the full supergranule model.

"supergranulex2_vz_xyt.fits"
data from a simulation of wave propagation through the full supergranule model with 
twice the supergranule flow magnitude.

"uniform_vz_xyt.fits"
data from a simulation of wave propagation through a uniform 100 m/s background flow in 
the Vx direction.
