Python and Matlab interfaces to the International Reference Ionosphere (IRI) 2020 model. A Fortran compiler is required to build the IRI2020 code.

Prerequisites

• Fortran compiler--any modern Fortran compiler will do. Here's how to get Gfortran:
  • Linux: apt install gfortran
  • Mac: brew install gcc
  • Windows Subsystem for Linux

and then install latest release:

if you want the latest development version:

This Python wrapper of IRI2020 uses our build-on-run technique. On the first run or iri2020.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 iri2020.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 iri2020.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 iri2020.times 2014-11-21 2014-11-22 1 -11.95 -76.77

IRI has a few dozen logical flags stored in variable JF. To reconfigure those flags, edit iri_driver.f90 and recompile iri2020_driver executable.

src/iri2020/data/{apf107.dat,ig_rz.dat} data files are regularly updated. Currently we don't auto-update those.
