SVCA Colegio Gaitan: Air Quality Monitoring Data for Bucaramanga, Jan-Jul 2025

January to July 2025 air pollutant measurements from the monitoring station at Colegio Jorge Eliécer Gaitán in Bucaramanga, Colombia. The dataset is part of the Air Quality Surveillance System (SVCA) operated by the regional environmental authority (CDMB) and includes real-time readings for particulate matter (PM10, PM2.5), sulfur dioxide (SO2), nitrogen dioxide (NO2), ozone (O3), and carbon monoxide (CO). Each measurement is accompanied by a validation flag indicating its quality status.

Use Cases

• Analyzing temporal trends of pollutants like PM2.5 and O3 using DATOS VALIDOS PM 2.5 and DATOS PLATAFORMA O3 over the 7-month period.
• Assessing data quality and sensor performance by cross-referencing pollutant readings (e.g., DATOS VALIDOS NO2) with their corresponding BANDERAS validation flags.
• Correlating meteorological parameters like temperature (DATOS VALIDOS T) and relative humidity (DATOS VALIDOS HR) with pollutant concentrations to study atmospheric influences.
• Comparing raw platform sensor data (DATOS PLATAFORMA PM10) with validated data (DATOS VALIDOS DV) to understand calibration and processing adjustments.

Strengths

• Includes a detailed validation flag system with 10 distinct statuses (e.g., VA, IC, IR) for assessing data quality per the 2017 Resolution 2254.
• Measures 7 key atmospheric pollutants (PM10, PM2.5, SO2, NO2, O3, CO, NOX) as indicated by columns like DATOS VALIDOS SO2 and DATOS PLATAFORMA NOX.
• Covers a specific 7-month time range from January to July 2025, providing a focused temporal snapshot.

Limitations

• The total number of rows and dataset size are unknown, which may limit suitability assessment for large-scale modeling.
• Metadata on license, author, and precise update frequency is unavailable, requiring manual verification.
• Data is from a single station (Colegio Gaitan), which may not be representative of the entire city of Bucaramanga.
