polycyclic aromatic hydrocarbons (PAHs). However, information about their distribution and …

Tropical glaciers are extremely sensitive to changes of climate variables. Their response to
climate change is complex and depends on multiple mechanisms affecting their mass and …

Surface albedo typically dominates the mass balance of mountain glaciers, though long-
term trends and patterns of glacier albedo are seldom explored. We calculated broadband …

Historically, glaciers have been seen as pristine environments. However, recent research
has shown that glaciers can accumulate and store contaminants over long timescales …

The fast retreat of the tropical Andean glaciers (TAGs) is considered an important indicator of
