Earth System Modeling Framework ESMF User Guide Version 3.0

The ESMF software is based on the contributions of a broad community. Below are the software packages that are included in ESMF or strongly influenced our design. We’d like to express our gratitude to the developers of these codes for access to their software as well as their ideas and advice. • The Spherical Coordinate Remapping and Interpolation Package (SCRIP) from Los Alamos, on which we based our regridding functionality with the help of SCRIP author Phil Jones • The Inpack configuration attributes package from NASA Goddard, which was adapted for use in ESMF by members of NASA Global Modeling and Assimilation group • The Flexible Modeling System (FMS) package from GFDL and the Goddard Earth Modeling System (GEMS) from NASA Goddard, both of which provided inspiration for overall ESMF structure • The Weather Research and Forecast (WRF) modeling system, on which we based our underlying I/O implemen-tation • The Common Component Architecture (CCA) effort within the DoE, from which we drew many ideas about how to design components • The Vector Signal Image Processing Library (VSIPL) and its predecessors, which informed many aspects of our design, and the radar system software design group at Lincoln Laborator
