Summary: | This major release of MPAS introduces the MPAS-Seaice core, and it includes new functionality, general improvements, and fixes to the Ocean, Land Ice, and Atmosphere cores. Also included are various small improvements, optimizations, and clean-up in the shared software infrastructure. Specific changes to each of the MPAS components are detailed below. Framework: Introduction of a new module for logging messages during model execution. Unless any errors are encountered, MPAS cores now write a single log file, named <code>log.<core>.0000.out</code>. In case errors occur, each MPI task will write its own error log file named <code>log.<core>. .err</code>. Performance enhancements to aggregated halo exchanges used in the Ocean, Land-ice, and Sea-ice cores. Minor enhancements to the MPAS "stream manager", including the ability to specify "final_only" for the "input_interval" or "output_interval" of a stream to read/write that stream only at the model stop time. Various bug-fixes and other clean-up to ensure that the framework can be used in coupled-model configurations involving more than one MPAS core. Atmosphere: Relative to the v5.0 release, the MPAS v6.0 release represents a minor increment in capability for the MPAS-Atmosphere core. MPAS-Atmosphere v6.0 includes: An increase of the default number of layers from 41 to 55 to match the standard experimental set-up used at NCAR. The addition of support for the use of GMTED2010 terrain elevation, matching the default terrain dataset used in the WRF model. Set <code>config_topo_data = 'GMTED2010'</code> in the namelist.init_atmosphere file when interpolating static fields. Computation of the GWDO sub-grid-scale orography fields in a way that is more consistent with the pre-computed fields used in the WRF model. Support for parallel builds of the <code>init_atmosphere</code> and <code>atmosphere</code> cores. Use <code>make -j N .</code>. A significant reduction in the size of model ...
