Abstract:  Accurate understanding of the spatiotemporal distribution of water resources is crucial for the sustainable development of arid regions. Here, we focus on the Arabian Peninsula and use satellite data to (i) analyze the local climatology of precipitation, soil moisture, and water storage, (ii) characterize their temporal variability and spatial distribution, and (iii) infer recent trends. Remote sensing data for precipitation, water storage and soil moisture were obtained from the Tropical Rainfall Measuring Mission (TRMM), the Gravity Recovery and Climate Experiment (GRACE), and the Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E), respectively. We first compare the GRACE retrievals to in situ groundwater well observations locally over the United Arab Emirates. Statistically significant decreasing trends in water storage were observed from both the GRACE data and well observations. The study relies on trend analysis, the modified Mann-Kendall test, and change point detection statistics. Decreasing ASMR-E trend coefficients were recorded in the southern part of the Peninsula and were spatially in line with the decreasing TRMM trends, while the highest decreasing GRACE trends were recorded in the northern part of the Peninsula, revealing the dominant macro-scale impacts of groundwater migration. Lag times for GRACE water storage peak response were consistently low (1 to 6 months) and high (6 to 12 months) over the northern, and southern parts, respectively, revealing the important impact of soil type, topography, and climatic disparities on the Peninsula’s water budget components.
