Detail Grid Data Harian

Panjang Data 28 tahun tersedia

R80 Rata-rata 2.60 mm/hari

Reff Padi Rata-rata 1.82 mm/hari

Reff Padi Maksimum 3.77 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.
