Solar Altitude & Azimuth: Zayed City, UAE

Direct answer

For Zayed City at 23.6542, 53.7052, the declination-only solar-noon altitude is approximately 89.8° at the June solstice, 66.3° at an equinox and 42.9° at the December solstice. Refine these geometry checks with the project date, civil time, facade azimuth, terrain and local horizon. The reproducible location record is GeoNames ID 291580 in administrative area 01, at 23.6542, 53.7052; replace it with the surveyed parcel point before relying on the result. As a transparent geometry check, declination-only solar-noon altitude is about 89.8° at the June solstice, 66.3° at an equinox and 42.9° at the December solstice. Representative 21st-day geometry ranges from about 10.5 hours in December to 13.5 hours in June; this excludes atmospheric refraction, terrain and obstruction effects. The cited national authority is a discovery starting point; current local documents and a named qualified reviewer control project use of this solar altitude and azimuth record.

What must be verified for Zayed City?

Zayed City is represented here at approximately 23.6542, 53.7052 for discovery and workflow planning. A project address, parcel, elevation, exposure, authority, and submission date must replace that city-centre reference before design use.

How should solar altitude and azimuth be established?

1. Fix the surveyed site and local time basis.
2. Select an authoritative weather source or a named solar-position algorithm.
3. Record period, percentile or scenario and units.
4. Test sensitivity to elevation, exposure, urban form and horizon.
5. Save the source file, retrieval date and checker in the model record.

What are the limits of this worksheet?

This solar-angle-workflow page is a project-starting worksheet, not a design value or approval. The controlling authority and qualified professionals for the Zayed City site remain authoritative.

Zayed City apparent-solar-time altitude and azimuth matrix

How to use the Zayed City angle matrix

The matrix fixes latitude 23.6542° and records longitude 53.7052°, but its clock column is apparent solar time rather than civil time. Convert the project date and longitude with a reviewed solar-position implementation before transferring an angle into a model. Azimuth is clockwise from true north. Rows below the geometric horizon are retained to make the screening limit visible; refraction, terrain and obstructions can change observed sunrise and sunset.

Harth calculated this solar altitude & azimuth matrix with the Cooper declination approximation and spherical altitude/azimuth equations. It is a reproducible comparison asset, not a surveyed horizon or construction setting. Refine it with the NREL Solar Position Algorithm.
