Re: Minimum computer requirements for running MPAS

That's correct. Again, the 0.175 MB/cell figure is a rough estimate. Using more cores will generally increase the model simulation rate, but if time is not an issue, a single MPI task running on a single hardware core will eventually finish any integration that could be done on more cores, as long ...

How to get title to display lat,lon instead of X,Y

Hello. I'm using RIP to plot vertical cross section of potential temperature. In my rip configuration file, I used crsa=-73.4lat,161lon and crsb=-75.2lat,165.75lon. The output in the plot currently says: Potential Temperature XY 74.1,75.8 to 88.6,56.1 I would like for the title output to use lat/lon...

Can you change FFLAGS = -O2 -ffree-form -Wall -DHAVE_NF90_INQ_VARIDS -I/home/ubuntu/install_mpas/libraries/include/ -L/home/ubuntu/install_mpas/libraries/lib/ -lnetcdf -lnetcdff to FFLAGS = -O2 -ffree-form -Wall -DHAVE_NF90_INQ_VARIDS -I/home/ubuntu/install_mpas/libraries/include/ -L/home/ubuntu/ins...

Error in WRF–ARW Online Tutorial Restart Run page

I was refreshing my memory regarding restart steps in WRF. In the Restart Run - wrf.exe page https://www2.mmm.ucar.edu/wrf/OnLineTutorial/CASES/Restart/wrf.php . You should have already completed the Single Domain Matthew Case before attempting a restart run. In the Single Domain case we started the...

mpas2wrf question.

I thought of using RIP4.7 to make plots for the output of regional MPAS-A 7.0. Which calls for the usage of https://github.com/NCAR/mpas2wrf to convert MPAS-A output to WRF grids. But I couldn't get it to work. I tried using netcdf-fortran package inside conda-forge ( to streamline the libraries use...

Working with LBC

Hi. Trying to produce a static fields for a relatively high resolution x1.2621442, takes a very long time and not feasible on a desktop PC. My question is, can you create a limited region from a grid file first, then create static fields from the smaller limited region grid file? For example, from x...

Re: Minimum computer requirements for running MPAS

Regarding memory requirements, we've found that a reasonable way to estimate the amount of memory needed to run a particular simulation is to multiply the number of horizontal cells in the mesh by 0.175 MB/cell; this estimate is based on a single-precision model run with around 55 vertical levels. ...

Re: How do you run the model from a different location.

Lastly, for the next release we are planning to release a shell script that will automatically set up the init_atmosphere and atmosphere cores in a desired directory, so be on the lookout for that. mcurry, yes, using those steps, I'm able to run MPAS from different folder. Didn't realise the actual...

How do you run the model from a different location.

I have gone through the 2019 Tutorial, all done in the root MPAS Model folder. Considering that I plan to run several case study with different time period (for example June 1990 and June 2018), using CFS (pre 2011) and CFSV2 (post 2010). I would like to have different folder for each case. I plan t...

Re: MPAS 7.0 A failed on pio1.f90.

It's a bit late. But I have successfully compiled it using the command: make gfortran CORE=init_atmosphere USE_PIO2=true PRECISION=single However, looking at ldd ./init_atmosphere libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007fddc397e000) I was expecting it to use the zlib compiled in the ins...

MPAS 7.0 A failed on pio1.f90.

Hello. I'm trying to compile MPAS 7.0 Atmosphere. For starter, I'm using this installation script, https://www2.mmm.ucar.edu/people/duda/files/mpas/sources/iolib_installation.sh . However instead of using netcdf-c-4.7.0 in the script, I'm using netcdf-c-4.7.4. This is due to problem with curl. Pleas...
