Water Density Variations of the Aral Sea from GRACE and GRACE-FO Monthly Solutions

The Gravity Recovery and Climate Experiment (GRACE) its successor, the GRACE Follow-On (GRACE-FO) gravity satellite missions, have been providing monthly field solutions for almost 20 years, enabling a unique opportunity to monitor large-scale mass variation processes. anomaly time series Aral Sea region has obtained period of April 2002 January 2022. method determining from GRACE-FO improved by considering variations Caspian Sea. was then compared water changes determined in salinity temperature seawater. Nevertheless, tests suggest that improvements correlation with such information might occur, although relevance improvement should not be overestimated. All all, it can demonstrated relevantly influence field; however, signal is too weak inversely obtain satellite-borne observations on variations.
