BioclimaMX Stations: Mexican Climate Station Records (CONAGUA), Augmented with NASA POWER

Daily observations and published climatological normals from 5524 CONAGUA conventional weather stations across Mexico (Servicio Meteorológico Nacional, Normales Climatológicas archive, consulted 2026-09-16), augmented with the 31 NASA POWER reanalysis variables of each station's grid cell on the 0.5° × 0.625° (latitude × longitude) grid: meteorology from MERRA-2, the 10 solar, radiation, and cloud streams from CERES. Observed daily series (maximum and minimum temperature, precipitation, evaporation): 71469869 rows across 5524 stations, 1877-03-06 to 2026-09-11. Normals cover the 4 reference periods 1961-1990, 1971-2000, 1981-2010, and 1991-2020. POWER daily reanalysis: 10138632 rows across 609 grid cells, 1981-01-01 to 2026-07-31; POWER monthly climatology for 1981-2010 and 1991-2020. The deposit holds per-state and national archives in CSV, Parquet, JSON, and SQLite, the raw CONAGUA snapshot, a generated data dictionary, provenance manifests, and a QA report.
