Solar elevation angle

The "solar elevation angle" is the elevation angle of the sun. That is, the angle between the directionof the sun and the (idealized) horizon. It can be calculated, to a good approximation, using thefollowing formula::$, sin heta_mathrm\left\{s\right\} = cos h cos delta cos Phi + sin delta sin Phi$where
*$, heta_mathrm\left\{s\right\}$ is the "solar elevation angle"
*$, h$ is the hour angle, in the local solar time.
*$, delta$ is the current sun declination
*$, Phi$ is the local latitude

* Altitude
* Horizontal coordinate system
* Solar azimuth angle
* Sun
* Sunrise
* Sunset
