MASS BALANCE MEASUREMENTS Snow accumulation (pits) ACCUMULATION AREA Equilibrium line Rain Ablation area Mass transference: Thickness , superficial speed Terminus Energy balance Length evolution Pits (density snow /ice , thickness) Stakes (ablation, speed) Hydrological station Standard device for glacier Total rain gauge ( snow/rain) monitoring over the Tropical Andes Automatic wheather station (AWS)

Mass balance annual structuring Location of equilibrium line altitude (ELA) Mass balance average over Glaciar 15 Antisana 551 mm we Eqilibrium line altitud placed in average 5125 m.a.s.l. Accunulation area ratio average AAR 0 for Glacier 15 of Antisana corresponds 63% of the total glacier coverage (21 years ) Cáceres et.al. 2016

Main programs that was made for INAMHI in relation with Cryosphere “Program a Glaciares Ecuador “ Instituto Nacional de Meteorología e Hidrología (INAMHI), in the way. Ecuador (continental) level. Glaciological mesearum ents in Antisana,Cotopaxi,Chimborazo,Carihuayrazo – in the way ; Altar,Cayambe in progress. “Program a Glaciológico Antártico Ecuatoriano ” Instituto Nacional de Meteorología e Hidrología (INAMHI) – Instituto Antártico Ecuatoriano (INAE) . Shetland Island- Antartic Peninsula – Greenwich Island; Pedro Vicente Maldonado Base . Glaciological measurem ents (2010-2017) “ MONI TOREO DE GLACI ARES TROPI CALES ANDI NOS EN UN CONTEXTO DE CAMBI O CLI MÁTI CO “ in the way, regional level (Colombia,Ecuador,Perú, Bolivia) Cooperation Interam erican Developem ent Bank (IDB) – Instituto Nacional de meteorología e hidrología (INAMHI)… … … … … .. Placed in Chimborazo and Carihuayrazo . “Glacioclim “ in the way. Cooperation IRD ( Institute pour Resercher and development –France) -Instituto Nacional de Meteorología e Hidrología (INAMHI). Glaciological work in Antisana (15 Alpha an Los Crespos). Support the operation and maintenance of Antisana 15 station and glaciological measurem ents. “CATCOS ( phase 2 ) – Capacity building and Tw inning for clim ate observing system ” ,recently completed. Reinforced field work in Antisana 15 Alpha by four years. Cooperation Meteoswiss- INAMHI.
