CGCAM Data for Plasma Modeling
The data provided in the links below was taken from the CGCAM simulation of
the 21 June 2014 case from the New Zealand DeepWave measurement campaign.
See the
simulation description
for more details on the simulation itself. The simulation was started at
08:00 UTC on 21 June and run for 8.5 hours (until 16:30 UTC). The surface
winds were gradually increased from zero to the ERA5-computed values over
the first four hours. Thus the data files given below start at 12:00 UTC.
The upper altitude wave pattern is still evolving strongly at 12:00 UTC,
and thus it might be better to choose fields between 14:00 and 16:000 UTC.
The CGCAM data was interpolated onto a uniform Cartesian mesh in the horizontal
directions with a spacing of 2 km. The origin for the x-y coordinate
system is at Mt. Cook (43.6032°S, 170.1440°E). The computational domain is
not centered on this point as the largest upper altitude response is not
directly overhead the high terrain. The x and y variables in the netcdf
files give the precise coordinate locations. The data is sampled on a
stretched grid in the vertical direction and extends from about 140 km to
about 371 in altitude. The height variable in the netcdf files gives the
precise locations of the vertical grid points.
The atmospheric gas properties vary with altitude and this inormation is
provided in the last file below.
