5+ Years of Multiple Time Series Data of Hourly PM2.5 Recordings Gathered from Various Sensors Located throughout Japan (1-1-2018 to 25-4-2023)|空气污染监测数据集|PM2.5数据数据集

Air pollution is the major cause for many respiratory related deaths in Japan. The Ministry of Environment Japan has setup a nation-wide sensor network to monitor air pollution throughout Japan. This network is called Atmospheric Environmental Regional Observation System (AEROS). More information on this is available at https://soramame.env.go.jp/

Here, we are providing the hourly recordings of PM2.5 values by 1000+ sensors from 1-1-2018 to 25-4-2023 (5+ years). Please consider the value 9999 means missing data. According to Japanese norms, values greater than 15 ppm3 is consider unhealthy.

We are providing three files:
a) station_info.csv : contains the station_id, address, and lat/long of the station
b) ETL_DATA_final.csv: Contains the PM2.5 hourly data of various sensors.
format of this data is: rowNumber,timestamp,sensor_1 values, sensor_2 values, ...
c) Soramame-key.pdf: Explains the process to convert this columnar multiseries data frame into a transactional database and extract patterns.
