Increased mass loss of glaciers in Volcán Domuyo (Argentinian Andes) between 1962 and 2020, revealed by aerial photos and satellite stereo imagery
International audience Abstract We present geodetic mass-balance estimates for ten glaciers (22.6 ± 1.1 km 2 ) around Volcán Domuyo between 1962 and 2020 (and 46 glaciers covering 29 ± 1.5 km 2 between 1984 and 2020), derived from airborne, ASTER and Pléiades imagery. Overall, we find a slightly neg...
