Sun Path: Ghāziābād, India

Direct answer

For Ghāziābād at 28.6654, 77.4391, the declination-only solar-noon altitude is approximately 84.8° at the June solstice, 61.3° at an equinox and 37.9° 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 1271308 in administrative area 36, at 28.6654, 77.4391; replace it with the surveyed parcel point before relying on the result. As a transparent geometry check, declination-only solar-noon altitude is about 84.8° at the June solstice, 61.3° at an equinox and 37.9° at the December solstice. Representative 21st-day geometry ranges from about 10.2 hours in December to 13.8 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 Ghāziābād?

Ghāziābād is represented here at approximately 28.6654, 77.4391 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.

Harth computed the Ghāziābād fingerprint for latitude 28.6654° with the Cooper declination approximation, 90° - |latitude - declination| at solar noon, centre-to-centre sunrise hour angle and 1 / tan(altitude) shadow ratio. Longitude 77.4391° is retained for a later civil-time conversion; this screen does not perform that conversion. See NOAA's solar calculation details. Atmospheric refraction, terrain, facade azimuth and obstructions remain outside this first-pass comparison.
