aldebaran1/NCAR-GLOW

CMake, Meson, Matlab, Python additions to GLOW. NCAR wants to publish only base code.

GLOW

The GLobal airglOW Model

• Fortran-90 source code files,
• Makefiles,
• Example input and output files,
• Example job script,
• Subdirectory data/ contains input data files,
• Subdirectory data/iri90 contains IRI input data files

Build

You can call this repo from a Meson wrap or CMake Fetch. To build by itself, do either:

meson build

ninja -c build

or

cmake -B build -S .

cmake --build build -j

MPI / NetCDF

The parallel version of GLOW requires MPI and NetCDF for TIEGCM I/O.

mpirun -np 2 ./mpi_glow.bin < ~/data/in.namelist.tgcm

Note, for an unknown reason, in.namelist.msis only works with -O0 or -O1 with gfortran 7. We didn't look into why. Otherwise, -O3 works fine.

Matlab / GNU Octave

The Matlab and Python interfaces work similarly. Matlab code is in the matlab directory, and passes data to / from Glow over stdin / stdout pipes.

• Use built-in energy and altitude bins: Simple.m
• user input energy grid: EnergyGrid.m

NOTE: if using GNU Octave, version ≥ 4.2 is required for proper textscan() functionality
