annual_timepercent_from_worst_month

pycraf.pathprof.annual_timepercent_from_worst_month(p_w, phi, omega)[source] [edit on github]

Calculate annual equivalent time percentage, p, from worst-month time percentage, p_w, according to ITU-R P.452-16 Eq (1).

Parameters
p_wQuantity

worst-month time percentage [%]

phiQuantity

Geographic latitude of path center [deg]

omegaQuantity

Fraction of the path over water (see Table 3) [%]

Returns
pQuantity

Annual equivalent time percentage [%]

Notes

  • Use this function, if you want to do path propagation calculations for the worst month case. The resulting time percentage, p, can then be plugged into other functions. If you want just annual averages, simply use your time percentage value as is.
