find_msis_file(; year=2018, month=12, day=7, hour=11, minute=15,
                lat=76, lon=5, height=85:1:700)

Find or create a MSIS model data file for the specified conditions.

It first searches for an existing MSIS file matching the given parameters. If no matching file is found, it calculates new MSIS data using the Python pymsis package and saves it to a file. The pymsis package will download, compile and run some fortran code under the hood.

Keyword Arguments

• year::Int=2018: Year
• month::Int=12: Month (1-12)
• day::Int=7: Day of month (1-31)
• hour::Int=11: Hour in Universal Time (0-23)
• minute::Int=15: Minute (0-59)
• lat::Real=76: Geographic latitude in degrees North
• lon::Real=5: Geographic longitude in degrees East
• height::AbstractRange=85:1:700: Altitude range in km

Returns

• String: Full path to the MSIS data file

Notes

• Default parameters correspond to the VISIONS-2 rocket launch conditions
• Files are stored in internal_data/data_neutrals/ directory

find_iri_file(; year=2018, month=12, day=7, hour=11, minute=15,
                lat=76, lon=5, height=85:1:700)

Find or create an IRI model data file for the specified conditions.

It first searches for an existing IRI file matching the given parameters. If no matching file is found, it calculates new IRI data using the Python iri2020 package and saves it to a file. The iri2020 package will compile and run some fortran code under the hood.

Keyword Arguments

• year::Int=2018: Year
• month::Int=12: Month (1-12)
• day::Int=7: Day of month (1-31)
• hour::Int=11: Hour in Universal Time (0-23)
• minute::Int=15: Minute (0-59)
• lat::Real=76: Geographic latitude in degrees North
• lon::Real=5: Geographic longitude in degrees East
• height::AbstractRange=85:1:700: Altitude range in km

Returns

• String: Full path to the IRI data file

Notes

• Default parameters correspond to the VISIONS-2 rocket launch conditions
• Files are stored in internal_data/data_electron/ directory
