# Climate grids

Two small, zlib-compressed rasters the integration uses to describe the home's
climate (Settings → Home profile, template recommendations). They are read with
the Python standard library only — see `helpers/climate.py` for the format.

| File | Content | Resolution |
|---|---|---|
| `koppen_0p5.bin` | Köppen-Geiger climate class 1991–2020 (1–30, 0 = water) | 0.5° |
| `temp_1p0.bin` | Coldest and warmest monthly mean air temperature 1991–2020 (°C) | 1° |
