Notes
This function creates a regular global grid in Geographic coordinates using given spatial resolution lon_res, lat_res. In case you want to run IRI in magnetic coordinates, you can obtain a regular grid in magnetic coordinates, then convert it to geographic coordinates using your own methods, and then use these 1-D alon and alat arrays. Similarly, if you are interested in regional grid, then use your own alon and alat 1-D arrays. alon and alat can also be irregular arrays. In case you need to run IRI for 1 grid point, define alon and alat as NumPy arrays that have only 1 element. Size of alon and alat is [N_G]. This function creates creates an array of altitudes for the veritical dimension of electron density profiles. Any 1-D Numpy array in [km] would work, regularly or irregularly spaced. This function also creates time array aUT using a given temporal resolution hr_res in hours. E.g. if hr_res = 0.25 it will lead to 15-minutes time resolution. You can define aUT your own way, just keep it 1-D and expressed in hours. It can be regularly or irregularly spaced array. If you want to run PyIRI for just 1 time frame, then define aUT as NumPy arrays that have only 1 element. Size of aUT is [N_T].
