Abstract

The temporal and spatial resolution of rainfall data is crucial for climate change modeling studies in which its variability in space and time is considered as a primary factor. Rainfall products from different remote sensing instruments (e.g., radar or satellite) provide different space-time resolutions because of the differences in their sensing capabilities. We developed an approach that augments rainfall data with increased time resolutions to complement relatively lower resolution products. This study proposes a neural network architecture based on Convolutional Neural Networks (CNNs) to improve temporal resolution of radar-based rainfall products and compares the proposed model with an optical flow-based interpolation method.
