Swanson et al., 2017 -- aeolianBedformSurfaceModel --Simulation #1 temporal subset as netCDF

<b>Summary:</b>Included netCDF file is a subset of simulation #1 results from Swanson et al., 2017 "A Surface Model for Aeolian Dune Topography" saved as a well-formatted netCDF file. <br><b>Details:</b>* default simualtion parameters were used.* only the first 500 timesteps of the simulation were recorded into the netcdf file.* the ordering for "easting" and "northing" coordinates in the netCDF file is opposite from the paper---the data are the same, but the source region is along the second axis; thus the display is different from the original paper.* simulation used the model code included as a supplement to the paper found here:https://static-content.springer.com/esm/art:10.1007/s11004-016-9654-x/MediaObjects/11004_2016_9654_MOESM5_ESM.txt<br>* simulation was executed on 12/02/2021 with Matlab R2021a on Ubuntu 20.04<br><b>Reference:</b>Swanson, T., Mohrig, D., Kocurek, G. et al.
