PENGGUNAAN CITRA MODIS SEBAGAI PENDUGA SUHU DALAM PERHITUNGAN EVAPOTRANSPIRASI DENGAN METODE BLANEY-CRIDDLE (STUDI KASUS: DAS CIMADUR, BANTEN)

Jurnal Ilmu Tanah dan Lingkungan, 2012
Evapotranspirasi (ET) merupakan komponen neraca air terpenting setelah curah hujan. Saat ini, pengukuran evapotranspirasi dapat dilakukan dengan menggunakan input data yang berbasis penginderaan jauh. Penelitian ini mengembangkan rumus empirik perhitungan evapotranspirasi, yaitu Blaney-Criddle, dengan memanfaatkan nilai Land Surface Temperature (LST ...
