Detail Grid Data Harian

Panjang Data 28 tahun tersedia

R80 Rata-rata 2.78 mm/hari

Reff Padi Rata-rata 1.94 mm/hari

Reff Padi Maksimum 3.38 mm/hari

Metode mengikuti pola modul TRMM hidrologi.net: data setengah bulanan diurutkan, probabilitas Weibull dihitung dengan m/(n+1), R80 diinterpolasi, kemudian hujan efektif padi = 70% × R80 per hari.

R80

INTERPRETASI

Nilai R80 menggambarkan curah hujan yang dapat diandalkan pada probabilitas 80%. Hujan efektif padi pada modul ini dihitung sebesar 70% dari R80 harian dan dapat digunakan sebagai input awal analisis kebutuhan air irigasi dengan tetap memperhatikan metode desain dan data lapangan yang digunakan pada studi.
