Derecho CLM-DART

• CLM-DART scripting updated for Derecho.
• CLM-DART SourceMods packaged with DART.
• Reinstituted both 'complete' and 'single_year' datm streamlist files in shell scripts
  due to delays when initializing the CAM reanalysis files through campaign/collections directory.

bug-fixes:

• Fixed format statement in assert_mod to conform to Fortran standards.
• Fixed debugging output for failed forward operators.

doc-fixes:

• Remove broken link for register for dart.

Developer tests and bug fixes

• new developer tests to run all builds for all compilers on NSF NCAR machine
  Derecho.
• removed redundant nc_check routine from utilities_mod in favor of
  netcdf_utilities_mod::nc_check
• Improved default thinning options for AIRS L2 converter.

bug-fixes:

• AIRS L2 converter message prints correct number of obs.
• MOM6 model_mod .eqv. used for logical comparison to conform to Fortran standard.

Note to developers: if you have your own code that makes use of DART's nc_check
replace use utilities_mod, only :: nc_check with use netcdf_utilities_mod, only :: nc_check

NSF documentation update

• Following official Policy on Brand Standards of the U.S. National Science Foundation for DART documentation.
• Changes instances of “NCAR” to “NSF NCAR” and adds NSF logo to the DART logo in the navigation menu.

Github Actions MPI f08 check

Adds a new check to the Github Actions workflow that uses the mpif08 module (compiles with ./quickbuild mpif08 and runs filter on 2 mpi tasks with the lorenz_96 model). #563

MPI f08 quickbuild option

new features:

• quickbuild.sh mpif08 option to build using the mpi_f08 module #261 #551 #497
• nvhpc mkmf.template for use on Derecho #554

bug-fixes:

• filter_mod.dopperlerfold in sync with filter_mod #565
• unnecessary loop removed from Mersenne twister developer test

doc-fixes:

• rename assim_model_mod.rst to match the module #282
• fix various Sphinx warnings and broken link #546

Quantile methods pre-release: QCEFF Table

Pre-release version of the quantile conserving and probit transform tools, including the new functionality of the QCEFF Table

The documentation for this branch is available online

Please contact [email protected] if you would like to develop scientific collaborations using these new capabilities.

Below is a list of the changes to quantile_methods that are included with this release:

• The QCEFF input table allows for the specification of QCEFF/probit input options, per QTY, at runtime.
• This replaces the functionality of using an algorithm_info_mod specific to the model, which meant editing algorithm_info_mod.f90 to specify which distribution should be used for which quantity.
• The algorithm_info_mod files for the lorenz_96_tracer_advection model examples have been replaced with set QCF tables (all_bnrhf_qcf_table.csv, all_eakf_qcf_table.csv, state_eakf_tracer_bnrhf_qcf_table.csv, neg_qcf_table.csv) and can be found in lorenz_96_tracer_advection/work.
• Removed the ‘global’ version of filter_kind from assim_tools_mod.f90 and the &assim_tools_nml

Hybrid EnKF-OI filter

A hybrid ensemble and optimal interpolation filter, combining flow-dependent ensemble covariances with time-invariant climatological backgrounds. The combination is done linearly and adaptively both in space and time.

For detail see El Gharamti, et al. (2024): Leveraging a Novel Hybrid Ensemble and Optimal Interpolation Approach for Enhanced Streamflow and Flood Prediction.

Note: This release is supported for WRF-Hydro only and is based on DART version v9.11.7

WRF-DART tutorial section on diagnostics

• Added a more complete diagnostics section to the WRF-DART Tutorial.
• Developer test for Mersenne twister random number generator. #499
• Bug-fix: 1D location subsetting fixed for obs_sequence_tool. #547 contributed by Henry Santer

Fluxnet observation converter and obs_def_rttov13_mod.f90 bug-fixes

Fluxnet obs converter (#478):

• Generates a new observation converter (Fluxnetfull_to_obs) for eddy covariance flux tower data (carbon, water energy fluxes)
• Documentation changes made to the older, deprecated ameriflux converter (level4_to_obs) and the broken links have been fixed
• New flux tower observation types added to accomodate the forward operator approach for time aggregated fluxes (daily through monthly)

obs_def_rttov13_mod.f90 bug-fixes:

• Added public get_channel to obs_def_rttov13_mod.f90 to compile WRF successfully with rttov13. #532
• Removed cloud_overlap (integer) from the function: get_rttov_option_logical #537

CAM-FV shell scripts

Performance improvements for CAM-FV shell scripts:

• Avoid listing files if the CAM_PHIS file already exists.
• Avoid using /var/tmp
• RUNDIR defined after CIME_OUTPUT_ROOT change.
• Warn if no inflation files found.
