Progressive Hypsometry and the glacial limitation of tropical mountain ranges

Analyses

Revealing glacial limitation of tropical mountain ranges

Mountain range DEMs are constructed from 1-arcsecond SRTM digital topography, which are available in 1° latitude x 1° longitude tiles. These tiles are mosaicked together to make the DEMs you see below. The color ramp for each DEM is pastel BYG from 0 to 500 m ASL, then GYR from 500 m - 3400 m ASL. The color ramp switches to dark blue-through-light blue from 3400-4500 m, representing the typical range of tropical snowlines (glacial equilibirum altitude, ELA). Area above the ELA band is white.
