Colombian Sea Level Observations from Automated Sensor Network

Nivel del Mar provides raw, unvalidated sea level observations from automated sensor stations across Colombia. The dataset is published by the Instituto de Hidrología, Meteorología y Estudios Ambientales (IDEAM) as open data under Law 1712 of 2014. Data was last updated in March 2026.

Use Cases

• Model temporal sea level trends using the FechaObservacion and ValorObservado columns.
• Analyze spatial distribution of monitoring stations using Departamento, Municipio, Latitud, and Longitud fields.
• Identify sensor-specific data streams or anomalies by joining records via CodigoSensor and CodigoEstacion.
• Categorize observations by hydrological region using the ZonaHidrografica column.

Strengths

• Includes 12 distinct columns for spatial, temporal, and measurement metadata.
• Data is published with high frequency, with a last update timestamp of 2026-03-09.

Limitations

• Data is explicitly unvalidated and may contain errors or inconsistencies from sensor failures.
• Observations may have time delays due to sensor transmission frequencies.
• Sample size and temporal coverage range are unknown.
