ERA5, küresel iklimin ECMWF atmosferik yeniden analizinin beşinci neslidir.
Yeniden analiz, model verilerini dünyanın dört bir yanındaki gözlemlerle birleştirerek küresel olarak eksiksiz ve tutarlı bir veri kümesi oluşturur. ERA5, önceki sürümü olan ERA-Interim yeniden analizinin yerini almıştır.
ERA5 MONTHLY, yedi ERA5 iklim yeniden analiz parametresi için her aya ait toplu değerler sağlar: 2 m hava sıcaklığı, 2 m çiğ noktası sıcaklığı, toplam yağış, ortalama deniz seviyesi basıncı, yüzey basıncı, 10 m rüzgarın u bileşeni ve 10 m rüzgarın v bileşeni. Ayrıca, 2 m'deki aylık minimum ve maksimum hava sıcaklığı, saatlik 2 m hava sıcaklığı verilerine göre hesaplanmıştır. Aylık toplam yağış değerleri, aylık toplamlar olarak verilir.
Diğer tüm parametreler aylık ortalamalar olarak sağlanır.
ERA5 verileri 1940'tan itibaren gerçek zamanlı olarak üç ay boyunca kullanılabilir. EE Veri Kataloğu'ndaki sürüm ise 1979'dan itibaren kullanılabilir. Daha fazla bilgi ve daha fazla ERA5 atmosferik parametre için Copernicus Climate Data Store'u ziyaret edin.
Sağlayıcının Notu: Aylık toplamlar, her parametrenin ERA5 saatlik değerlerine göre hesaplanmıştır.
