Deep Learning Augmented Data Assimilation: Reconstructing Missing Information with Convolutional Autoencoders

Remote sensing data play a critical role in improving numerical weather prediction (NWP). However, the physical principles of radiation dictate that data voids frequently exist in physical space (e.g., subcloud area for satellite infrared radiance or no-precipitation region for radar reflectivity)....
