Ionospheric and tropospheric screens
The mid_simulations.py python script, which is used to generate various simulated data for the SKA Mid telescope, uses ionospheric and atmospheric screens in the form of FITS file fo two of its simulation modes:
ionospheretroposphere
These screens are generated using the python code described at Screens. They use the ARatmospy package under the hood, which needs to be installed. For python3, use the forked version at https://github.com/timcornwell/ARatmospy.
There is also a Makefile provided, which simplifies running the right commands for generating the files. A detailed description of how one can do this can be found in the code README.
The files are also available on the Google Cloud Platform.
