Sun Path: Minna, Nigeria

Direct answer

For Minna at 9.6152, 6.5478, the declination-only solar-noon altitude is approximately 76.2° at the June solstice, 80.4° at an equinox and 56.9° 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 2330100 in administrative area 31, at 9.6152, 6.5478; replace it with the surveyed parcel point before relying on the result. As a transparent geometry check, declination-only solar-noon altitude is about 76.2° at the June solstice, 80.4° at an equinox and 56.9° at the December solstice. Representative 21st-day geometry ranges from about 11.4 hours in December to 12.6 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 sun path record.

What must be verified for Minna?

Minna is represented here at approximately 9.6152, 6.5478 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 sun path 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.
