Climate normals and Köppen-Geiger classification: Beck et al. (2023), Scientific Data 10, 724, CC BY 4.0. Period 1991–2020. Classification resolution ≈ 1 km; monthly climate data resolution ≈ 1 km (0.01°, Original 2023 release; predates the January 2026 correction), sampled at the grid cell containing the city coordinates (39.90°, 116.41°). Climate normals describe the long-term average, not current weather.
