KOREKSI BIAS ESTIMASI CURAH HUJAN PADA SATELIT GPM-IMERG DI PULAU JAWA

Megasains, 2022
Kelengkapan data curah hujan di tiap tempat cukup sulit didapatkan karena minimnya ketersediaan data dan jumlah pos hujan maupun stasiun yang tidak tersebar secara merata. Permasalahan ini dapat diatasi dengan menggunakan satelit, seperti satelit GPM-IMERG, di mana memiliki resolusi spasial dan temporal yang tinggi.
