New Delhi has witnessed a sharp spike in industrialization within a very short time frame. The primary source of pollution in Delhi is the pollutants coming from meteorological activities, vehicles and heavy industries. In this study, pollutant data from four locations in Delhi - Anand Vihar, DTU, Bawana and Vivek Vihar have been analysed. In this paper, the dataset from the Delhi Air Pollution Control Board has been used.1 The critical reason for choosing the pollutant Particulate Matter 2.5 is because of its lethal nature. In this paper, multivariate analyses have been done with the help of Long Short Term Memory (LSTM) -deep learning methodologies. Recent versions of LSTM like the Encoder-Decoder-LSTM, Bi-Directional LSTM, and LSTM-Forward Neural Network have also been implemented and analysed. In terms of novelty, this paper implements the technique (ten steps ahead or multistep ahead) short-term air quality forecasting method. In this paper, one month’s future air pollutant Particulate Matter 2.5 predictions have been done. In addition, twelve predictor variables with eighty hours of data have been used. The accuracy of the models has been evaluated with the help of the Root Mean Square Error evaluation matrix. The impact of the Covid-19 lockdown in Delhi has also been investigated, and it was evaluated that the air quality deteriorated once the restrictions were relaxed. It was evaluated that the bi-directional LSTM with the least RMSE error was the best prediction model.
