Accurate data collection and time series creation are crucial for understanding these changes. However, many areas lack reliable due to geopolitical issues government permissions. Urgent action is needed sustainable water management. This study uses Gravity Recovery Climate Experiment (GRACE) analyze monthly fluctuations in groundwater storage the Missan region of Iraq from January 2022 December 2023, using Goddard Space Flight Center (GSFC) mascon, Jet Propulsion Laboratory Downscaled (JPL_D), Catchment Land Surface Model (CLSM). revealed variability GWS over area RS integration with available monitoring wells. To investigate variability, GSFC, JPL_D, CLSM observed a downward trend 2022; GSFC exhibits highest negative trend, while has lowest trend. Then, June had positive Most period remote sensing that matches well situ, which wells 1, 2, 4 trends period. In conclusion, results improve role small-scale unconfined aquifers, supports decision-making resource The findings illustrated match between derived GRACE data.

<p>Recent studies show that groundwater depletion is an unreported source of atmospheric CO₂ through bicarbonate reactions in the released from aquifer. However, can be mitigated or offset by recharge, and thus contrasting roles recharge on carbon cycle remain unclear at a national scale. Here, we extend previous to use satellite–derived storage change (GWSC) substantial situ measurements ion concentration (BIC), for first time evaluation GWSC–induced emission/sequestration China. Results GWSC represents as significant China, with net emission rate 2.1±2.3 Mt/yr, which larger than 15% sources listed China Carbon Emission Accounts Datasets. Besides, sequestration induced (GWS) decrease increase also significant, 3.9±1.1 Mt/yr 1.8±1.2 respectively. Notably, find China’s stricter measures contribute total reduction 5.3 Mt major overdraft areas 2025. Despite notable uncertainties, this study highlights unneglectable contributions global scale.</p>
