Description

Collection of MPAS 8 vs MPAS 7 differences.

User reported problems with MPAS 8 and DART:

  • MPAS reconstructed wind no longer output by mpas
    Change made to MPAS which has removed uReconstruct{Zonal,Meridional}' fields from atmosphere restart stream.

    https://github.com/MPAS-Dev/MPAS-Model/pull/1016

    Required (at least with the current DART mpas model_mod) for assimilating wind. The model_mod is assuming
    uReconstruct{Zonal,Meridional} are present in the restart file.
