MPAS-Dev/MPAS-Model: MPAS Version 7.1

This minor release addresses several issues in the MPAS-Atmosphere model and initialization, and it corrects several minor compilation issues. MPAS-Atmosphere: In calculating moist air density in the real-data initialization case, virtual temperature, rather than temperature, should be used. An out-of-bounds array access in the GWDO scheme when running with multiple OpenMP threads has been corrected. A check has been added in the init_atmosphere core to ensure that the intermediate file interval and the 'surface' stream output interval are consistent. A non-standard BOZ-literal constant has been corrected in the module_ra_cam_support.F file. The non-standard constant lead to build failures, particularly with newer versions of the GNU compilers. General software: The logic to add PIO libraries to the definition of LIBS in the top-level Makefile has been updated to accommodate newer versions (approx. 2.5.2 or later) of the PIO library; without the fix to the Makefile, builds would fail with the messageChecking for a usable PIO library... ************ ERROR ************ Failed to compile a PIO test program Please ensure the PIO environment variable is set to the PIO installation directory ************ ERROR ************ Various options for the 'gfortran' build target have been cleaned up. Occasional parallel build failures related to a race condition in the ezxml library compilation have been addressed.
