AN EXPLAINABLE CONVOLUTIONAL AUTOENCODER MODEL FOR UNSUPERVISED CHANGE DETECTION

The large amount of information regularly acquired by satellites can provide important information about SWE. We explore the use of multi-source data, in-situ observations and a degree-day melting model to reconstruct daily SWE at 25 m. The results show spatial patterns that are consistent with the geomorphological features as well as with a reference product. Being able to also reproduce inter-annual variability, the method has great potentiality for hydrological and ecological applications.
