MPAS-Bundle V4.0 release note (6/10/2026)
- MPAS-Bundle v4 is based on MPAS v8.4.1 and the JEDI 2026.1 release.
- Generic model-variable naming conventions have been introduced in most MPAS-JEDI source code and yaml files. For example, variables that we previously denoted
uReconstructZonal, uReconstructMeridional, temperatureare noweastward_wind, northward_wind, air_temperature. This gives mpas-jedi easy access to generic JEDI capabilities, such as SABER’s spectral B. - A bugfix for the
geopotential heightvariable change, which is required for GNSS RO operators, has been made in MPAS-JEDI. This bugfix makes the fit-to-obs statistics much improved for GNSS RO observations. - The MPAS-JEDI ctest suite has been improved, including re-generation of the dataset and modifying the yaml configurations. A ctest with a regional MPAS mesh was also added.
- MPAS-Bundle v4 optionally includes the ioda-converters repository. NCAR's observation-processing code "obs2ioda" has been moved from an external repository to ioda-converters and incorporates additional contributions from the JCSDA core team.
- The computational efficiency of MPAS-JEDI has improved, such as i) avoiding the re-initialization of B in the Variational applications with the multiple outer loops and ii) using linearized observation operators in the EnKF applications.
