A Feedforward Neural Network for ESA CCI Soil Moisture Disaggregation

IGARSS 2024 - 2024 IEEE International Geoscience and Remote Sensing Symposium
This study presents a methodology for disaggregating the ESA Climate Change Initiative (CCI) Soil Moisture (SM) maps from 0.25° to a 60 m grid, using a feedforward neural network. This technique is applied over an area of 66,700 km2 , encompassing parts of Oklahoma and Kansas (US), throughout 2021.
