  • Global co-occurrence of warm temperature extremes and terrestrial water storage deficits

    Open AccessAshraf Rateb, Bridget R Scanlon et al.ARTICLEEnvironmental Research Letters2025

    Compounding climate extremes threaten ecosystems, agriculture, and public health, with intensification driven by a warming climate and increasing human interventions. However, the global linkage between temperature extremes and total water storage (TWS) deficits remains insufficiently explored. Here, we analyzed 22 years (2002–2024) of Gravity Recovery and Climate Experiment (GRACE) and GRACE-FO satellite data to examine the spatiotemporal coinci…

  • Effects of climate and irrigation on GRACE-based estimates of water storage changes in major US aquifers

    Open AccessBridget R Scanlon, Ashraf Rateb et al.ARTICLEEnvironmental Research Letters2021

    Understanding climate and human impacts on water storage is critical for sustainable water-resources management. Here we assessed climate and human drivers of total water storage (TWS) variability from Gravity Recovery and Climate Experiment (GRACE) satellites compared with drought severity and irrigation water use in 14 major aquifers in the United States. Results show that long-term variability in TWS tracked by GRACE satellites is dominated by…

  • Linkages between GRACE water storage, hydrologic extremes, and climate teleconnections in major African aquifers

    Open AccessBridget R Scanlon, Ashraf Rateb et al.ARTICLEEnvironmental Research Letters2021

    Water resources management is a critical issue in Africa where many regions are subjected to sequential droughts and floods. The objective of our work was to assess spatiotemporal variability in water storage and related controls (climate, human intervention) in major African aquifers and consider approaches toward more sustainable development. Different approaches were used to track water storage, including GRACE/GRACE Follow On satellites for T…

  • How can Big Data and machine learning benefit environment and water management

    Open AccessAlexander Y Sun, Bridget R ScanlonARTICLEEnvironmental Research Letters2019

    Big Data and machine learning (ML) technologies have the potential to impact many facets of environment and water management (EWM). Big Data are information assets characterized by high volume, velocity, variety, and veracity. Fast advances in high-resolution remote sensing techniques, smart information and communication technologies, and social media have contributed to the proliferation of Big Data in many EWM fields, such as weather forecastin…

  • Is southwestern China experiencing more frequent precipitation extremes

    Open AccessMeixian Liu, Xianli Xu et al.ARTICLEEnvironmental Research Letters2014

    Climate extremes have and will continue to cause severe damages to buildings and natural environments around the world. A full knowledge of the probability of the climate extremes is important for the management and mitigation of natural hazards. Based on Mann–Kendall trend test and copulas, this study investigated the characteristics of precipitation extremes as well as their implications in southwestern China (Yunnan, Guangxi and Guizhou Provin…
