Unraveling the contributions of atmospheric rivers on Antarctica crustal deformation and its spatiotemporal distribution during the past decade
SUMMARY Atmospheric rivers (ARs) are efficient mechanisms for transporting atmospheric moisture from low latitudes to the Antarctic continent. AR events induce intense snowfall episodes, which increase crustal deformation. Here, we used an AR detection algorithm, via a spatial matrix operation to qu...
