Colombian Precipitation Measurements from Automated Weather Stations

Rainfall amounts recorded every 10 minutes at automated weather stations across Colombia, verified with basic quality control per World Meteorological Organization (WMO) recommendations. The data is provided by the Instituto de Hidrología, Meteorología y Estudios Ambientales (IDEAM) via the www.datos.gov.co platform and was last updated on April 3, 2026. Values failing quality checks have been corrected or removed, though additional verification is recommended for sensitive or specialized technical uses.

Use Cases

• Analyze precipitation behavior and identify extreme weather phenomena using ValorObservado and FechaObservacion.
• Conduct regional climate studies by aggregating data by Departamento or Municipio.
• Map rainfall distribution and station density using Latitud and Longitud coordinates.
• Correlate precipitation with hydrographic zones using ZonaHidrografica and ValorObservado.

Strengths

• Data undergoes basic quality control aligned with WMO recommendations, with erroneous values corrected or removed.
• Includes precise geospatial coordinates (Latitud, Longitud) and administrative divisions (Departamento, Municipio) for location-based analysis.
• Temporal granularity is high with observations recorded every 10 minutes (FechaObservacion).

Limitations

• The provider notes data may contain errors, inconsistencies, or transmission delays and should not be used as legal evidence.
• Row count and total dataset size are unknown, limiting suitability assessment for large-scale projects.
• Description metadata is limited; actual data quality requires manual inspection after download.
