AG100: مجموعة بيانات الانبعاثات العالمية من ASTER بدقة 100 متر، الإصدار 003
تم تطوير قاعدة بيانات الانبعاثات العالمية لراديومتر الانبعاثات الحرارية والانعاكس الفضائي المتقدّم (ASTER-GED) من قِبل مختبر الدفع النفاث (JPL) التابع لإدارة الطيران والفضاء الأمريكية (NASA) في معهد كاليفورنيا للتكنولوجيا. يتضمّن هذا المنتج متوسّط انبعاثات الحرارة والانحراف المعياري لجميع قنوات الأشعة تحت الحمراء الحرارية الخمسة في ASTER … aster elevation emissivity geophysical infrared jpl -
