About This Dataset
The data provides daily measurements for various pollutants (such as SO2, NO2, and SPM) for different locations in Delhi. It is useful for historical environmental studies.
Data Quality
The dataset is structured and consistent with numeric measurements for pollutant concentrations. Some fields contain missing values represented as NA, particularly in the RSPM/PM10 column and occasionally in SO2 values. Sampling dates are formatted consistently but may require parsing into date format during preprocessing.
Use Cases
Urban air quality monitoring, historical pollution trend analysis, environmental health research, policy evaluation for pollution control, and academic studies on urban environmental conditions.
Limitations
The dataset is limited to one city and a single year. It does not include meteorological variables, geographic coordinates of stations, or measurement units for pollutant concentrations. RSPM/PM10 data appears unavailable in the provided records.
Methodology
The measurements were likely collected through air quality monitoring stations operated by the Central Pollution Control Board. Pollutant concentrations were measured periodically at residential and industrial monitoring sites and recorded as part of routine environmental monitoring programs.
