-A coupler is a software used to perform simulations with different model components at the same time. The coupler enables the different model components to exchange information during the simulation.
+A coupler is a software package that allows synchronised exchanges of coupling information between numerical codes representing different components of the climate system.

-The NUOPC interoperability layer is distributed via the Earth System Modelling Framework (ESMF). It is a coupler developed by the National Unified Operational Prediction Capability (NUOPC), a consortium of Navy (USA), NOAA and Air Force (USA) modelers. 
+[NUOPC][NUOPC-int-layer] (National Unified Operational Prediction Capability) Interoperability Layer defines conventions and a set of generic components for building coupled models using the Earth System Modeling Framework (ESMF).

+ACCESS-OM3, a configuration currently under development, uses [NUOPC to couple its MOM6 and CICE6 model components][coupler-choice] as there are no respective OASIS coupling interfaces for these components.
