Abstract: Atmospheric contamination can pose a severe threat to the health of people and incur kinds of diseases,thus,forecasting the concentration of atmospheric contaminant can be of great significance for instructing the atmospheric pollution control.To solve the issue,we propose a kind of mixed forecasting model based on LSTM and full connected neural network,and we introduce the training strategyof data bucket,which can address the issue that the long interval between training data and forecasting sample.Our model has a high performance on both versatility and precision,we fully combine the advantages of LSTM and full connected together and achieve high precision forecasting with varieties of contaminants.Finally,we take an example of forecasting of Tianjin to validate its strength and the results show that our model can achieve R2>0.90,MSE＜0.15performance for all six kinds of pollutant.It shows that LSTM-FC Model has its great strength for atmospheric contaminant concentrations task.

Key words: Atmospheric contaminant forecasting, Full connected neural network, Hybrid neural network model, Long short-term memory neural network, Multi-dimension feature fusion
