Beijing PM2.5 Data Set
Pollution Level Forecasting
This intermediate level data set has 43824 rows and 13 columns. This hourly data set contains the PM2.5 data of US Embassy in Beijing. Meanwhile, meteorological data from Beijing Capital International Airport are also included. The data seet could be used for pollution level forecasting using the Air quality attributes provided. This data set will offer experience in Multi-variate Time Series Forecasting.
This data set is recommended for learning and practicing your skills in exploratory data analysis, data visualization, and regression modelling techniques. Feel free to explore the data set with multiple supervised and unsupervised learning techniques. The Following data dictionary gives more details on this data set:
