# .AixLib.BoundaryConditions.SolarGeometry.BaseClasses.Examples.Declination

Test model for declination

## Information

This model validates the computation of the solar declination, which is the angle between the equatorial plane and the solar beam. The time table `solDecNOAA` outputs the solar declination according to the computation of the National Oceanic and Atmospheric Administration (NOAA), using their yearly calculator from http://www.esrl.noaa.gov/gmd/grad/solcalc/calcdetails.html. The values differ slightly because the equation in AixLib.BoundaryConditions.SolarGeometry.BaseClasses.Declination is an approximation.
