# solar elevation angle derivations

1. solar elevation angle from solar zenith angle

   symbol | description | unit | variable name
   --- | --- | --- | ---
   \(\alpha_{0}\) | solar elevation angle | \(deg\) | solar_elevation_angle {:}
   \(\theta_{0}\) | solar zenith angle | \(deg\) | solar_zenith_angle {:}

   The pattern : for the dimensions can represent {time}, or no dimensions at all.

   \[\alpha_{0} = 90 - \theta_{0}\]
