What is ESMF?
The Earth System Modeling Framework
(ESMF) is software for building and coupling weather, climate, and
related models. Read more about ESMF.
For Python users, ESMPy
offers the power of ESMF grid remapping through an easy to use interface.
The National Unified Operational Prediction
Capability (NUOPC) and its research partners are working toward a common model architecture -
a standard way of building models. The NUOPC Layer defines conventions and templates for using
ESMF, and makes it simpler to adopt the framework.
Learn more about the NUOPC Layer.
ESMF in the Earth System Prediction Capability: Under a new ONR
award, ESMF is working with partners from the Navy, NCAR, Argonne National Laboratory,
and other centers to bring the HYbrid Coordinate Ocean Model (HYCOM)
into the Community Earth System Model, and to increase the efficiency
of coupled systems on accelerator-based computing platforms.

Introducing Cupid: The ESMF team, together with partners from NASA and the Georgia
Institute of Technology, received a new
award from NASA to develop Cupid, a training environment for ESMF. Work under the Cupid award includes bringing
the GISS Model E climate model into ESMF, and enabling users to modify and run it through Cupid.

ESMF in NCL: ESMF 5.2.0rp2 regridding functionality has been incorporated into the 6.1.0-beta version of
the NCAR Command Language (NCL) visualization software.
ESMF adds fast parallel regridding, higher-order
interpolation, and additional grid support. The additional grid support enables bilinear, first-order
conservative, and new higher-order interpolation methods to be supported on curvilinear grids and
unstructured meshes as well as rectilinear grids.

Only interested in generating interpolation weights?
ESMF has the option to build a standalone application that can generate
interpolation weights in parallel (RegridWeightGen). It's fast
and can handle a wide variety of grids and grid options. It's not
necessary to use the rest of ESMF to use it ... just provide grid files in
a standard (netCDF-based) format.
Read more about the RegridWeightGen application here.
