About MeteoMate

MeteoMate tries to describe the weather not as a pile of numbers but as a sentence that tells you what to do about it. The same rules run on the website and in the app, so you read the same weather in the same words in both places.

Data sources and licences

For each country, whichever source is best there:

• Türkiye — MGM station observations and MeteoAlarm warnings, with the ECMWF IFS 9 km model for the forecast.
• The Netherlands — KNMI's 10-minute station observations and national warnings; the forecast uses HARMONIE-AROME 2.5 km for the first ~2.5 days, then ECMWF.
• The rest of the world — Google Weather.
• Lightning and radar (Türkiye) — MGM lightning tracking and composite radar images.
• UV index — CAMS (Copernicus Atmosphere Monitoring Service).
• AI answers — Google Gemini, only when you ask a question.

ECMWF and HARMONIE forecasts come via Open-Meteo (CC BY 4.0).

The city list holds 4,511 places: Turkish provinces and districts from the MGM list, Dutch places from the official PDOK (Kadaster) registry, and world cities from GeoNames (CC BY 4.0).
