Abstract

Global soil moisture products were developed based on different combinations of existing soil moisture datasets and methods in this study. These products are gap-free, long-term, and multi-layer. I think the developed soil moisture products will be important given the lack of global and consistent soil moisture observations. The soil moisture datasets used to create the products were based on different techniques (e.g., remote sensing, modeling) and different specifications (e.g., soil depth, time step). Merging them together is a challenging task.
