Abstract

This resource contains seasonal estimates of global characteristics of surface soil moisture preferential hydrologic states using SMAP observations from March 2015- September 2022. Three tipping characteristics are defined to estimate the intensity (Mean Tipping Depth, epsilon_bar), frequency (Tipping Count, eta), and duration (Mean Tipped Time, tau_bar) of the excursion of SMAP soil moisture from wet− to dry−average conditions.
For details, please refer to our affiliated paper here: Sehgal and Mohanty, Preferential Hydrologic States and Tipping Characteristics of Global Surface Soil Moisture (2023, WRR); https://doi.org/10.1029/2023WR034858
