What's New
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.
Read more on how to use ESMF in NCL. May, 2012
ESMF in UV-CDAT: The ESMF python interface, ESMP, is now used in the
Ultrascale Visualization - Climate Data Analysis Tools
(UV-CDAT) 1.0 software. ESMP provides bilinear and conservative regridding for curvilinear
gridded data. UV-CDAT receives primary support from the Department of Energy. May, 2012
ESMF Internal Release 5.3.0: New features include 3D conservative regridding and
fault tolerance. ESMP additions include support for logically rectangular grids as well as meshes, and
interfaces for all ESMF interpolation methods. There's more ... read
the release notes and download. April, 2012
Updated Component Listing: See the latest
listing of ESMF components and coupled modeling applications. April, 2012
ESMF in Space Weather Modeling: A new impacts page describes how ESMF regridding
is used in the Thermosphere-Ionosphere-Mesosphere-Electrodynamics General Circulation Model (TIMEGCM)
at the NCAR High Altitude Observatory.
April, 2012
ESMF Patch Release 5.2.0rp2: An update to the 5.2.0r release, this patch includes support
for clockwise cells in the conservative regridding capability.

ESMF Strategic Plan 2012-2015: The
ESMF Executive Board has approved a concise
ESMF Strategic Plan that addresses the need for end-to-end workflows, more comprehensive
model metadata, new computing architectures, and other challenges. February, 2012
Introducing ESMP: The prototype ESMF-Python (ESMP) library is a Python interface to ESMF grid
remapping functions. Currently only unstructured meshes are supported,
but updates and releases are happening frequently.
Visit the ESMP home page and try it out. February, 2012
Deprecation Policy: The
new deprecation policy addresses the timeline and process for making
changes to interfaces that have been identified as backward compatible. January, 2012

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.
