−34 cm

Syria's fall in stored water from 2003 to 2025, from +5.7 to −27.9 cm.

−27 cm

Iran over the same years, the country famous for its water crisis.

2nd

Syria's fall ranks behind only Chile among 92 large countries outside the ice sheets; Chile's includes melting Patagonian ice.

NASA/JPL GRACE and GRACE-FO Mascon CRI RL06.3Mv04, PO.DAAC, DOI 10.5067/TEMSC-3JC634. Total water storage anomaly (groundwater, soil moisture, lakes, snow and ice) against the 2004.0–2009.999 mean, cm equivalent water thickness. Country means of the monthly grid computed by progrss (Natural Earth 50m country mask, countries of 150,000 km² or more), then yearly means; 2003 has 11 of 12 months. Ranking among 92 countries: Greenland and Norway (ice-sheet and glacier loss) excluded; Chile's fall includes Patagonian icefield loss. Native resolution 3° mascons: neighbouring countries blur; coastal leakage uncorrected. Cite Watkins et al.
