Figure 1. Current SHiELD configurations. Each plotted cell is
48x48 actual grid cells. Heavy black lines represent cubed-sphere edges;
red lines represent nested grids. Note that the global domain of
C-SHiELD (top center) is slightly stretched as per Harris et al. (2019).
Although all configurations follow the unified “one code, one
executable, one workflow” structure of SHiELD, the configurations are
not identical owing to the need to tailor each configuration for its
specific application. Further, given the rapid pace of SHiELD
development and the staggered development cycle for some of the
configurations, we do not expect all of the Tier-1 configurations to
always have the very latest developments. The development paths of the
different SHiELD configurations can be seen in Table 1.
