Simple UFS Weather App

Welcome to the Simple UFS Weather App

Let's start with a disclaimer.

Disclaimer

This is unofficial, unsupported, untested and undocumented UFS Weather App. For official, supported, tested and documented UFS Weather App look elsewhere. For example here.

By cloning, forking or downloading anything from this repository I assume you know what you are doing.

What is in this repository

The purpose of this repository is to store my personal scripts I use to build UFS Weather model in a simple and portable way. Emphasis is on providing fairly simple building of all dependencies and model itself on a workstation type of computer (desktop/laptop) using GNU compilers.

That's all.

Quick start

Build

Run:

./get.sh

to download preprocessor, model, post processor and all dependencies.

Run:

./build.sh <gnu|intel>

to build (almost) everything.

This build script expects compilers (C, C++ and Fortran) and MPI library to be installed and available. Some basic development tools are also required, like standard unix tools, git, gmake, cmake, python2.7, perl. Either install required packages using you distribution package manger (yum/dnf, apt, apk, etc.), or load appropriate modules (if you are on a system that uses environment modules).

There's also an option to build MPI library [MPICH(v3.3.1) and OpenMPI(v4.0.2)] locally, run libs/mpilibs/build.sh script, and update your PATH to point to locally built library (for example libs/mpilibs/local/mpich3/bin).

Test your build

1. Clone the repository containing pre-generated input data for global C96 configuration. Initial date: 2016-10-03 00Z

git clone https://github.com/DusanJovic-NOAA/ufs-test-data

2. Run the model executable on 8 tasks:

cd ufs-test-data
mpiexec -np 8 <path>/simple-ufs/bin/ufs_model

This will run global C96 grid configuration. If the run is successful you'll find a number of output files named dynf???.nc (dynamics variables) and phyf???.nc (physics variables) in the run directory.

For reference and comparison, here are two example plots. Temperature at level 30 and total precipitation (24h forecast)

*** Good luck! ***

Hi @DusanJovic-NOAA
I've tried this section: https://github.com/DusanJovic-NOAA/simple-ufs#test-your-build

am I missing something here?
Thank you.

run_post fails on macOS with GNU compilers

Recording the issue - I could reproduce the problem on my Mac, which should make it easier to debug.
