Description
CDMB's Air Quality Surveillance System (SVCA) provides real-time atmospheric pollutant data from an automatic monitoring station on the Club Unión terrace in Bucaramanga. The dataset covers January to July 2025 and includes measurements for particulate matter (PM10, PM2.5), sulfur dioxide (SO2), nitrogen dioxide (NO2), tropospheric ozone (O3), and carbon monoxide (CO). Each data point is accompanied by a validation flag indicating its quality status.
Use Cases
Analyzing temporal trends of pollutants like PM2.5 and O3 using the FECHA Y HORA and DATOS VALIDOS columns.
Assessing data quality and filtering records by applying the BANDERAS validation flags to columns like DATOS VALIDOS NO2 or DATOS VALIDOS SO2.
Comparing raw sensor readings (DATOS PLATAFORMA) with validated measurements (DATOS VALIDOS) for instrument performance analysis.
Modeling correlations between different pollutants, such as NO, NOX, and NO2, using their respective validated data columns.
Strengths
Includes a detailed validation flag system with 11 distinct statuses (e.g., VA, IC, IR) for quality control.
Covers 7 key atmospheric pollutants (PM10, PM2.5, SO2, NO2, O3, CO, NOX) as indicated by the column names.
Data is reported in near real-time from an automated monitoring station, as described.
Limitations
Metadata completeness is limited; row count, license, and author are unknown, which may limit suitability assessment.
The temporal coverage is limited to a 7-month period from January to July 2025.
