As in glaciology, periglacial processes also occur in tropical regions, where altitude is the main controlling factor. Intertropical mountains that rise above the treeline (~ 4000 m a.s.l.) are exposed to various surface freezing dynamics, whether permanent, seasonal, or diurnal. However, the high elevation where periglacial dynamics occur means that in situ studies are scarce and observations are temporally limited. Consequently, atmosphere-soil interactions in tropical high mountains remain po
