Climate change directly impacts climatic factors like temperature and precipitation, resulting in devastating natural disasters. Soil moisture (SM) (defined as the water contained in the unsaturated soil zone) is a long-term indicator when investigating climate change. It plays a crucial role in water, energy, and carbon flow between soil and the atmosphere (McColl et al., 2017). SM could also be a factor in predicting and monitoring floods and droughts (Hu et al., 2020). Thus it is essential to have SM at suitable spatial scales, potentially enhancing the representation of hydrological and weather prediction in evapotranspiration, runoff, and precipitation models (Alemohammad et al., 2018). SM is the most important indicator of a region's water availability and climate change impacts. This was realized in the 1960s when Palmer Drought Severity Index was developed primarily based on SM variations. Palmer (1965) and many other relevant works have continued on SM measures as a driving force in regional water resources planning. Its position has been realized as the key basic hydrogeological data especially with the recent advances in SM data collection instrumentations, SM networking such as what is implemented in Oklahoma (Mesonet), and satellite technology advancement (Karamouz et al., 2022;McPherson et al., 2007). Although many in situ SM networks are available online but the scarcity of SM data in many developing regions is a serious issue that prevents a full advantage of utilizing this vital data in water balance assessments. Having satellite SM data with finer than resolutions is a breakthrough to allow these regions to exercise the benefits of SM in drought and flood studies. Karamouz, Ebrahimi, and Ghomlaghi (2021), combined citizen science subjective SM and MODIS satellite Land surface temperature (LST) (500 km resolution) data to estimate SM data in a remote area in the central part of Iran. Wildfire is another side effect of climate change around the world that has its casual roots in the reduction of SM. SM influences vegetation growth conditions. Dry vegetation and its root increase the flammability of the vegetation/trees. However, owing to a lack of global observation-based SM data, previous studies have focused on case studies at local to regional scales. Benefitting from recent advances in the satellite-based derivation of surface SM, new studies have been performed, analyzing on the global scale the role of SM in the occurrence of large wildfires (Hou & Orth, 2020).Flood is one of the most catastrophic natural disasters in the United States, particularly in the Southeast, where hurricanes and tropical storms are most prevalent, causing billions of dollars in damage annually and significant
