Air mass
If the sun is below the horizon, Air mass = -1.0000. Toggle the checkbox to enable/disable column in report.
Air mass Calculation
Airmass = 1.0/(cos(90 - elev) + 0.50572 * (6.07995 + elev)-1.6364)
Solar Zenith Angle
Solar elevation in Degrees from zenith (90°). Angles are corrected for atmospheric diffraction. Toggle the checkbox to enable/disable column in report.
Elevation:
Solar elevation in Degrees above horizon (0 degrees). Angles are corrected for atmospheric diffraction. Toggle the checkbox to enable/disable column in report.
Azimuth:
Sun azimuth, 0° = N, 90° = E, 180° = S, 270° = W. Toggle the checkbox to enable/disable column in report.
