Calculate sunrise and sunset time
显示 更早的评论
Hi all,
I wish to know if it's possible to calculate sunrise and sunset time using one date/time and geographical position ? Maybe a toolbox already exists ?
Thanks,

After I searched for and found that script, I discovered that Scripps Institute of Oceanography has a large collection of MATLAB files and toolboxes:

The connection between hour angle H, latitude phi and declination of sun delta is: cos(H) = -tan(phi)*tan(delta). delta can be approximated by: delta = sin(T)*23.5 where T is time from 21th, March or 23rd, September in days. Gives good enough results +- 20 min when you assume that H is 0 deg at noon.
