About
Data details air pollution measurements collected across the state of São Paulo, Brazil. This resource is valuable for performing exploratory data analysis aimed at developing a clear overview of the atmospheric pollution situation. By tracking pollutant concentrations over a long period, the material helps justify the environmental and public health impacts and allows researchers to verify the evolution of this significant problem. The dataset includes measurements for 9 distinct pollutants, such as MP10, O3, NO2, MP2.5, CO, SO2, NO, FMC, and PTS.
Columns
The dataset contains 10 attributes detailing the measurement events:
- ID: The unique integer index identifying each specific record (primary key). This field is 100% valid across all 11 million records.
- Data: The date on which the pollutant concentration measurement was taken. Records span from the beginning of 2015 to the end of 2021.
- Hora: The specific time when the measurement was recorded.
- Estação: The physical location or station where the measurement was performed. There are 87 unique stations identified, with 'Santos - Ponta da Praia' being one of the most frequently logged locations (3%).
- Código: The specific code associated with the measuring station. There are 87 unique codes recorded, with 'SP64' being a common example (3%).
- Poluente: The specific pollutant whose concentration was measured. There are 9 unique pollutants in the dataset, with MP10 (26%) and O3 (24%) being the most common.
- Valor: The concentration value of the pollutant measured. All records are valid, with the mean value recorded at 83.3.
- Unidade: The unit of concentration used for the measurement. This value is uniformly recorded as ug/m3 (100%).
- Tipo: Indicates how the measurement was conducted (e.g., automatic or manual). The 'automatica' type accounts for 100% of the recorded entries.
Distribution
The material is stored as a CSV file named
SP_poluicao_dados.csv, which has a large file size of 902.98 MB. The dataset structure includes over 10 million total lines (11.0m valid records). All documented columns maintain perfect data quality, showing 100% validity with no missing or mismatched entries.Usage
