Summary: The study finds that the soil-borne fungal disease coccidioidomycosis (Valley fever) in the southwestern United States is associated with anomalously wet or dry soil moisture states. The El Nino Southern Oscillation (ENSO) has a significant influence on both the occurrence of the infection and the soil moisture, with a shorter periodicity in Arizona and a longer periodicity in central California.

Summary: This study investigated the possibility of explaining hydrograph recession coefficients using satellite-derived soil moisture products, and found that drier river basins characterized by larger soil moisture variability tend to exhibit larger and more variable recession coefficients.

Summary: This study compares several state-of-the-art satellite soil moisture products for landslide applications, with results showing that the SMAP L4 product is beneficial for continuous landslide monitoring and has more rational spatial distribution of the correlation between soil moisture and antecedent cumulated rainfall. The Bayesian analysis on infiltration events indicates that the 'SMAP L4 root zone soil moisture'-derived events improve the prior knowledge of landslide occurrence probability, highlighting its potential for landslide hazard assessment.

Summary: This study evaluated the accuracy of four satellite-based soil moisture products in northern China by analyzing their spatial distribution and variability in different seasons and climate zones. The results showed that the satellite products performed best in summer and had large biases in winter. The CCI product performed well in arid climate zones, while SMAP and SMOS products had large biases in the eastern monsoon region.

Summary: This study estimated the lifetime cost-of-illness associated with all cases of Valley fever diagnosed in Arizona in 2019, with a total estimated cost of $736 million. Direct costs accounted for over 90% of expenditures, while indirect costs were around $65 million. Disseminated infection produced the highest economic burden, while primary uncomplicated pneumonia cases had the lowest costs.

Summary: This study proposes an ANN method to reconstruct missing surface soil moisture records with good agreement with ground-based observations, especially in regions with low-density vegetation. The ANN model outperformed the OK model in reconstructing SM with absent swaths and in densely and sparsely vegetated regions.

Summary: The monitoring of soil moisture and sea surface salinity has been greatly improved in the past thirteen years with the use of new satellite sensors. L-band radiometry is currently the only technology that can directly measure soil moisture and sea surface salinity from space, unaffected by surface roughness or soil composition. The SMOS and SMAP satellite missions provide global and local variability information at a spatial resolution of approximately 43 km and a temporal sampling of at least twice every 3 days, which can be further enhanced by merging data from multiple sensors or with in situ information.

Summary: Groundwater is vital for the earth's water and energy balance, but the lack of high spatiotemporal resolution observations hinders our understanding of its interactions with surface soil moisture. This study successfully estimated the global spatial and temporal distributions of shallow groundwater using a machine learning algorithm and satellite observations. The results showed that 19% of terrestrial land cover had been influenced by shallow groundwater. The study demonstrates the potential of using satellite observations for high-resolution global monitoring of shallow groundwater and its applications in environmental studies.

Summary: The study utilized an ensemble of multiple Kernel K-nearest neighbors models to predict soil moisture in Delaware, USA and surrounding watersheds, achieving lower spatial error and better predictive performance over time with downscaled estimates. These estimates displayed stronger temporal relationships with vegetation phenology and emphasized the need for improved in situ soil moisture monitoring for diverse landscape settings.

Summary: The Tibetan Plateau, known as the "Third Pole" of the world, is extremely sensitive to global climate change. This study assessed the performance of four satellite soil moisture products over the Tibetan Plateau and found that ESA CCI and SMAP-SCA performed better, with error sources related to GLDAS Noah soil moisture.

Summary: This study compares different satellite-based soil moisture products with ground-based measurements, taking into account factors such as geographic heterogeneity and land cover. The results show that SMAP L4 and ESA CCI perform the best, ASCAT performs the best among non-modeled/blended products, and SMOS-IC performs slightly better than CGLS SSM 1 km.

Summary: This study proposed a multi-satellite soil moisture retrieval method based on signal-to-noise ratio observations for BDS MEO and IGSO satellites, showing that BDS MEO B1I estimation results had the best performance. BDS IGSO's B1I signal was more suitable for soil moisture retrieval than the B2I signal.

Summary: This study investigates the relationship between surface organic carbon content and soil moisture dynamics in the Alaska North Slope. The results show that the drydown process of soil moisture in Arctic tundra is closely related to the surface soil organic carbon properties. The study suggests that satellite L-band observations are sensitive to tundra soil moisture and carbon properties.
