Brief Communication: Recent estimates of glacier mass loss for western North America from laser altimetry
Glaciers in Western North American outside of Alaska are often overlooked in global studies, because their potential to contribute to changes in sea level is small. Nonetheless, these glaciers represent important sources of freshwater, especially during times of drought. Differencing recent ICESat-2...
