Annual Air Quality and Meteorological Averages for Colombia

Annual averages of atmospheric pollutants and meteorological parameters collected by Colombia's Institute of Hydrology, Meteorology and Environmental Studies (IDEAM). The data is reported by regional environmental authorities to the SISAIRE subsystem, as mandated by Resolution 651 of 2010. It includes measurements for specific years, with the dataset last updated on 2026-05-18.

Use Cases

• Analyzing spatial pollution trends using `Nombre del Municipio`, `Latitud`, `Longitud`, and `Promedio` from 28 available columns.
• Identifying high-exceedance areas by correlating `Días de excedencias` and `Porcentaje excedencias limite actual` with `Tipo de Estación`.
• Modeling relationships between pollutant levels (`Variable`, `Promedio`) and weather conditions using `Mínimo`, `Máximo`, and `Mediana`.
• Assessing data representativeness and station performance by evaluating `Representatividad Temporal` and `No. de datos`.

Strengths

• Includes 28 columns covering pollutant levels, meteorological data, station metadata, and exceedance statistics.
• Data is officially mandated and reported by multiple regional environmental authorities to a national system (SISAIRE).
• Geographic specificity is provided with columns for municipality, department, and station coordinates (`Latitud`, `Longitud`).

Limitations

• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Description metadata is limited; actual data quality requires manual inspection after download.
