 \subsubsection{Introduction}
 The fizhi (high-end atmospheric physics) package includes a collection of state-of-the-art
 physical parameterizations for atmospheric radiation, cumulus convection, atmospheric
-boundary layer turbulence, and land surface processes.
+boundary layer turbulence, and land surface processes. The collection of atmospheric
+physics parameterizations were originally used together as part of the GEOS-3
+(Goddard Earth Observing System-3) GCM developed at the NASA/Goddard Global Modelling
+and Assimilation Office (GMAO).
