I was wondering how the 13-month smooth F10.7 solar flux obtained from the MSAFE files is converted to the daily and 81-day average solar flux to use with NRLMSISE-00
Welcome back to the forum!
Have you looked into MarshallSolarActivityFutureEstimation class already?
If not, I invite you to do it, all your answers are in there
In a nutshell:
- Mean flux@t: weighted mean (weight based on elapsed time from a point) between two points around t in MSAFE F10.7 solar flux.
- Daily average@t = Mean flux @ t - 1day
- 81-day average@t = arithmetic mean of Mean flux on the interval [t - 40days, t + 41days]
Hope this helps,
