abstract = "{The snow-fed river basins of the Near East region are facing an urgent
threat in the form of declining water resources. In this study,
we analyzed several remote sensing products (optical, passive
microwave, and gravimetric) and outputs of a meteorological
reanalysis data set to understand the relationship between the
terrestrial water storage anomalies and the mountain snowpack.
The results from different satellite retrievals show a clear
signal of a depletion of both water storage and the seasonal
snowpack in four basins in the region. We find a strong
reduction in terrestrial water storage over the Gravity Recovery
and Climate Experiment (GRACE) observational period,
particularly over the higher elevations. Snow-cover duration
estimates from Moderate Resolution Imaging Spectroradiometer
(MODIS) products point towards negative and significant trends
up to one month per decade in the current era. These numbers are
a clear indicator of the partial disappearance of the seasonal
snow-cover in the region which has been projected to occur by
the end of the century. The spatial patterns of changes in the
snow-cover duration are positively correlated with both GRACE
terrestrial water storage decline and peak snow water equivalent
(SWE) depletion from the ERA5 reanalysis. Possible drivers of
the snowpack depletion are a significant reduction in the
snowfall ratio and an earlier snowmelt. A continued depletion of
the montane snowpack in the Near East paints a bleak picture for
future water availability in this water-stressed region.}",
