Air Quality Monitoring Data from Hospital Local Norte, January-July 2025

CDMB's Air Quality Surveillance System (SVCA) provides real-time atmospheric pollutant data from a station on the roof of Hospital Local del Norte. 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 PM10 and O3 using DATOS VALIDOS PM10 and DATOS VALIDOS O3 columns.
• Assessing data quality and reliability by filtering records based on the various BANDERAS (flag) columns.
• Correlating different pollutant levels, such as NOX and CO, using DATOS VALIDOS NOX and DATOS VALIDOS CO columns.
• Validating sensor readings by comparing raw platform data (e.g., DATOS PLATAFORMA SO2) with validated data (DATOS VALIDOS SO2).

Strengths

• Includes a detailed validation flag system with 11 distinct status codes (e.g., VA, IC, IR) for assessing data quality.
• Covers a specific 7-month time range (January–July 2025) from a known monitoring station location.
• Monitors multiple key atmospheric pollutants as mandated by Colombian Resolution 2254 of 2017.

Limitations

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