Abstract: The cryosphere in South America is a very important resource because it is the main source of water for 85 million inhabitants distributed in Colombia, Ecuador, Peru, Bolivia, Chile and Argentina [1-2]. To know the effects due to global phenomena such as arctic oscillation (AO) in the reduction of the cryosphere in this region, we proceeded to analyze sources of reanalysis information (ERA-40; NCEP/NCAR Reanalysis) and high resolution snow cover (MOD10 500m) from Moderate-Resolution Imaging Spectroradiometer (MODIS). Several linear adjustments were made to observe how snow cover variations (Y) responded to variations in AO (X1 ), surface temperature (X2 ) and snow precipitation (X3 ).
