NOGAPS-ALPHA was developed at NRL from 2000-2011 as
a high-altitude prototype of the Navy’s global atmospheric forecast
and data assimilation system. The success of this project led to cessation of
further NOGAPS-ALPHA development and a frozen configuration at the
end of 2011,
as NRL moved to transition components of this prototype to a
successor NAVGEM system that replaced NOGAPS in February 2013.
However, this frozen NOGAPS-ALPHA system continues to
be used as a scientific research tool.
