ERA5 adalah analisis ulang atmosfer ECMWF generasi kelima untuk iklim global.
Analisis ulang menggabungkan data model dengan pengamatan dari seluruh dunia ke dalam set data yang lengkap dan konsisten secara global. ERA5 menggantikan pendahulunya, analisis ulang ERA-Interim.
ERA5 MONTHLY memberikan nilai gabungan untuk setiap bulan untuk tujuh parameter analisis ulang iklim ERA5: suhu udara 2 m, suhu titik embun 2 m, total presipitasi, tekanan permukaan laut rata-rata, tekanan permukaan, komponen angin u 10 m, dan komponen angin v 10 m. Selain itu, suhu udara minimum dan maksimum bulanan pada ketinggian 2 m telah dihitung berdasarkan data suhu udara pada ketinggian 2 m per jam. Nilai total presipitasi bulanan diberikan sebagai jumlah bulanan.
Semua parameter lainnya diberikan sebagai rata-rata bulanan.
Data ERA5 tersedia dari tahun 1940 hingga tiga bulan dari waktu real-time, versi di Katalog Data EE tersedia dari tahun 1979. Informasi selengkapnya dan parameter atmosfer ERA5 lainnya dapat ditemukan di Copernicus Climate Data Store.
Catatan Penyedia: Agregat bulanan telah dihitung berdasarkan nilai per jam ERA5
dari setiap parameter.
