GRIDMET DROUGHT: CONUS Drought Indices
تحتوي مجموعة البيانات هذه على مؤشرات الجفاف المستمدة من مجموعة بيانات "الشبكة المتداخلة للأرصاد الجوية على سطح الأرض" (GRIDMET) اليومية التي تبلغ مساحتها 4 كيلومتر. تشمل مؤشرات الجفاف المقدَّمة مؤشر هطول الأمطار الموحّد (SPI) ومقياس الطلب على الجفاف التبخيري (EDDI) ومقياس التبخر بالترسبات المعياري (SPEI) ومقياس Palmer لخطورة الجفاف (PDSI) ومقياس Palmer … المناخ المخروط المحصول الجفاف التبخر النتحي geophysical -
SPEIbase: قاعدة بيانات مؤشر التبخر بالترسبات المعياري، الإصدار 2.10
تقدّم قاعدة بيانات SPEI العالمية (SPEIbase) معلومات قوية على المدى الطويل عن حالات الجفاف على النطاق العالمي، مع حجم بكسل يبلغ 0.5 درجة ووتيرة شهرية. وتوفّر مقاييس زمنية لمؤشر SPEI تتراوح بين شهر واحد و48 شهرًا. يعبّر مؤشر التبخر بالترسبات المعياري (SPEI) عن متغيّر موحّد على النحو التالي: المناخ التغيّر المناخي الجفاف التبخر النتحي عالمي شهري -
TerraClimate: Monthly Climate and Climatic Water Balance for Global Terrestrial Surfaces, University of Idaho
TerraClimate هي مجموعة بيانات عن المناخ الشهري وموازنة المياه المناخية للمسطحات الأرضية العالمية. ويستخدم هذا النموذج الاستقراء بمساعدة المناخ، ما يجمع بين القيم العادية للمناخ ذات الدقة المكانية العالية من مجموعة بيانات WorldClim، والبيانات ذات الدقة المكانية الأقل دقة ولكن المتغيرة بمرور الوقت من CRU Ts4.0 وبرنامج إعادة التحليل الياباني الذي يمتد على 55 عامًا (JRA55). … المناخ الجفاف التبخر النتحي geophysical عالمي merced
