About this project
An open India temperature platform. Multiple independent sources, side-by-side comparison, hyperlocal ground sensors where they exist.
What's in the map
- 39 city points — current temperature from Open-Meteo (state capitals + metros)
- 570 OpenAQ stations — India ground sensors, 509 from CPCB regulatory network + 34 AirGradient + others
- 4,647 grid cells at 0.25° (≈ 27 × 25 km each) covering India's full claim — mainland + Andaman & Nicobar + Lakshadweep + Jammu & Kashmir (incl. PoK) + Ladakh (incl. Aksai Chin). Polygon: datameet/maps, simplified. This matches the native resolution of the ECMWF/ERA5 model that Open-Meteo serves.
Data sources
Open-Meteo (open-meteo.com) — free, no key, AGPLv3 server, CC BY 4.0 data. Provides current, forecast, and historical archive (ERA5).
OpenAQ v3 (openaq.org) — aggregates CPCB + community sensors. Requires free API key.
Natural Earth 50m — country polygon used to clip the grid to India landmass.
What's gated
IMD public API — api.imd.gov.in/api/v1/aws_data, /current_wx, /districtrainfall, /cityforecast exist and are documented, but all endpoints respond 401 API key missing. No public signup; access by formal request to aws.imd@gov.in.
data.gov.in CPCB realtime — endpoint reachable but the dataset itself carries only air-quality pollutants (PM2.5, NO2, etc.), no temperature column.
WRI India / CSTEP — heat-vulnerability and climate-risk products are published as PDFs and pre-rendered choropleths, not as tile services.
