| Abstract(in English) | In this paper, we developed a model for SR using ConvLSTM to improve the resolution of precipitation data. In the related work, SISR using SRCNN, it is difficult to recover local values for precipitation data. In this study, we propose a method that adds atmospheric variables to the low-resolution precipitation data and treats it as a time series data. The proposed model is based on ConvLSTM, which treats images as time series. In this evaluation, we compared the proposed model with the high-resolution precipitation data generated by SRCNN using the evaluation indices RMSE (Root Mean Square Error) and CC (Correlation Coefficient). The results show that the proposed model is 0.93 times more accurate in terms of RMSE and 13.25 times more accurate in terms of correlation coefficient for high-resolution precipitation data. |
