### Use case right now we have filter_mod.f90 and filter_mod.dopplerfold.f90 which requires developers to update both when they make changes. there seems to be an easy way to consolidate these...
### Describe the bug If an ob has an "incoming" QC value that denotes "do not use", then filter assigns the DART QC = 6 and assigns MISSING_R8 to the...
The snow fraction obs converter [documentation is incomplete](https://docs.dart.ucar.edu/en/latest/observations/obs_converters/snow/snow_to_obs.html). This applies for both `snow_to_obs.f90` (text file) and `snow_to_obs_netcdf.f90` (netcdf file). Although it appears both converters are meant to operate on the...
Hit this while working with TIEGCM: There is a module netcdf_utilities_mod, but it looks like the state io makes almost no use of netcdf_utlities_mod (execpt nc_check). e.g. location_io_mod, direct_netcdf_mod, state_structure_mod....
### Describe the bug In reviewing the mpas_atm model_mod code, the subroutine find_vert_indices() calls find_vert_level() which calls find_height_bounds(). find_height_bounds uses either the zGridCenter array or the zGridEdge for vertical locations....
### Use case The mpas_atm model_mod has supported having W (vertical wind velocity) in the state vector, but there is no code to support interpolating the W value at a...
In order to conduct coupled data assimilation experiments, @amrhein plans to use a CESM B compset configured as follows: - CAM6 atmosphere; CICE sea ice; POP2 ocean - data assimilation...
### Use case It would be very helpful to people who use CESM+DART if the released versions of CESM have been tested to ensure that they provide the functionality required...
direct_netcdf_io.f90: ``` 2933 !================================================= 2934 ! Routines for distributing data round-robbin 2935 !================================================= !> This code has multiple places where round-robin layout of state onto task is assumed. !> These...
### Use case What are you trying to accomplish? Sometimes there may already be a way to do what you need. I'm working data assimilation for space weather and find...
