ESA-satellieten zoals Envisat en Sentinel-1 hebben daarbij geholpen. Wolken kunnen het zicht van de satellieten blokkeren, maar met radarapparatuur kunnen ze door de wolken heen kijken naar de gletsjers eronder. Ondanks dat zijn er tijden en plekken waarvan de wetenschappers geen satellietgegevens hadden. Om die lege plekken in te vullen, maakten ze gebruik van een geavanceerde computersimulatie om te voorspellen wat er met de gletsjers gebeurde.<\/p>\n<p>ESA-satellieten blijven gletsjers in de gaten houden, foto's maken en gegevens verzamelen. Die informatie is onmisbaar voor ons op aarde, omdat we moeten zien hoe onze planeet verandert en wat we eraan kunnen doen!<\/p>\n<p><b>Leuk weetje:<\/b> 10% van het landoppervlak van de aarde is bedekt met gletsjers!<\/p>","protected":false},"excerpt":{"rendered":"<p>Scientists have been using satellites in orbit around Earth to monitor a group of 30 frozen glaciers in Antarctica.
