Python and Matlab interfaces to the International Reference Ionosphere (IRI) 2016 model. A Fortran compiler is required to build the IRI2016 code.
Prerequisites
apt install gfortran
brew install gcc
and then install latest release:
pip install iri2016
if you want the latest development version:
git clone https://github.com/space-physics/iri2016
pip install -e iri2016
This Python wrapper of IRI2016 uses our build-on-run technique.
On the first run or iri2016.IRI()
the Fortran code is built–we call this “build on run”.
If you have errors about building on the first run, ensure that your Fortran compiler is specified in environment variable FC–this is what most build systems use to indicate the desired Fortran compiler (name or full path).
Altitude Profile: plot density and temperatures vs altitude
python -m iri2016.altitude 2003-11-21T12 -11.95 -76.77
Latitude profile: plot densities and height at the peak of F2, F2, and E regions vs geographic latitude
python -m iri2016.latitude 2004-11-21T17 -76.77
Time profile: plot densities and height at the peak of F2, F2, and E regions vs UTC
python -m iri2016.time 2014-11-21 2014-11-22 1 -11.95 -76.77

irisub.for has a few dozen logical flags stored in variable JF. To reconfigure those flags, edit iri2016_driver.f90 and recompile iri2016_driver.exe.
IRI2016 is readily accessible from Matlab. From within Matlab verify everything is working by:
