GLIMS 2023: מדידות גלובליות של קרח יבשתי מהחלל
Global Land Ice Measurements from Space (GLIMS) היא יוזמה בינלאומית שמטרתה למדוד שוב ושוב את 200,000 הקרחונים המשוערים בעולם. מטרת הפרויקט היא ליצור מלאי מקיף של קרח יבשתי ברחבי העולם, כולל מדידות של שטח הקרחון, הגיאומטריה שלו, מהירות פני השטח שלו וקו השלג… cryosphere glacier glims ice landcover nasa -
