Sea Surface Temperature (SST) has a significant impact on weather and climate. A problem in recording SST is presented by clouds that cover certain areas of the sea surface, thus preventing measurements in these areas. As a result, SST measurements are incomplete, making their use for short- and long-term weather forecasting more difficult. Various reconstruction approaches have been proposed to solve this problem, including the DINCAE2 method based on two consecutive autoencoders. In this thesis, we propose an approach that enhances the DINCAE2 method by using Fourier transformation. We add a parallel autoencoder to the DINCAE2 method that uses Fourier transformation, and then combine the results of both branches. With this, we managed to lower the RMSE of SST reconstruction by 34 % compared to the DINCAE2 method. With the adapted loss function, we reduced RMSE by 40 % compared to the DINCAE2 method.
