abstract = "{The Arctic freshwater budget is critical for understanding the climate
in the northern regions. However, the hydrology of the Arctic
circumpolar tundra region (ACTR) and the largest pan-Arctic
rivers are still not well understood. In this paper, we analyze
the spatiotemporal variations in the terrestrial water storage
(TWS) of the ACTR and three of the largest pan-Arctic river
basins (Lena, Mackenzie, Yukon). To do this, we utilize monthly
Gravity Recovery and Climate Experiment (GRACE) data from 2002
to 2016. Together with global land reanalysis, and river runoff
data, we identify declining TWS trends throughout the ACTR that
we attribute largely to increasing evapotranspiration driven by
increasing summer air temperatures. In terms of regional
changes, large and significant negative trends in TWS are
observed mainly over the North American continent. At basin
scale, we show that, in the Lena River basin, the autumnal TWS
signal persists until the spring of the following year, while in
the Mackenzie River basin, the TWS level in the autumn and
winter has no significant impact on the following year. As
expected global warming is expected to be particularly
significant in the northern regions, our results are important
for understanding future TWS trends, with possible further
decline.}",
