- OpenIFS 48r1 ECbuild/cmake build system
- the build system has been changed from FCM to ECbuild/cmake. This change means that
- OpenIFS uses the same build system as the IFS and can therefore capitalise on the pre-existing build options such as enablling single and/or double precision
- Makes the creation of OpenIFS from IFS easier
- Associated changes in OpenIFS build scripts, please see Build OpenIFS 48r1
- the build system has been changed from FCM to ECbuild/cmake. This change means that
- OpenIFS 48r1 can be built using single and/or double precision
- OpenIFS includes CAMS chemistry and aerosol at cycle as the IFS cycle, i.e. 48r1, by default
- Thus, as well as an upgrade, this release consolidates OpenIFS and OpenIFS-AC into one code base, with one development workflow.
- More aligned with the IFS
- OpenIFS 48r1 includes the single column model (SCM) and builds SCM alongside the 3-D model by default
- OpenIFS 48r1 includes ifs-test with
- 21 t21 tests of forecast-only functionality with and without chemistry
- 1 SCM test
- ifs-test can be used to
- validate installation, i.e., validate the build and basic simulation capability
- genarate "known good output" for a given system and compiler, which can be used to test any code changes
