Sat\u00e9lites de la ESA como el Envisat y el Sentinel-1 han estado contribuyendo a esta tarea. A veces las nubes les ocultan los glaciares a la vista, pero los radares que llevan a bordo permiten atravesarlas para verlos. A pesar de ello, ha habido momentos y lugares en los que los cient\u00edficos no pod\u00edan recibir datos de los sat\u00e9lites. Para rellenar esos vac\u00edos, utilizaban una sofisticada simulaci\u00f3n por ordenador con la que pod\u00edan deducir qu\u00e9 estaba ocurriendo con los glaciares.<\/p>\n<p>Los sat\u00e9lites de la ESA seguir\u00e1n vigilando esas enormes masas de hielo, captando im\u00e1genes y recopilando datos.
