Abstract

Reliable rainfall data is crucial for managing water resources, especially in agricultural regions like the Bodor Sub Watershed. This study comprehensively evaluates two precipitation products, the satellite-based CHIRPS dataset and the reanalysis ERA 5 dataset within the Bodor Sub Watershed. Both products were compared against gauge data at three timescales (monthly, 15-days, 10-days) for seven locations (Bodor Sub Watershed region and six rain gauges). Statistical parameters, including Nash Sutcliffe Efficiency (NSE), RMSE-observation standard deviation ratio (RSR), Pearson correlation coefficient (CC), and percent bias (PBIAS), were used to assess the performance of each precipitation product. Results consistently demonstrate that ERA 5 outperforms CHIRPS in most locations and time scales, particularly monthly. ERA 5 exhibited superior performance in over 85% of the analyses, with NSE values ranging from 0.164 to 0.862, RSR values from 0.992 to 0.372, and CC values from 0.507 to 0.932. ERA 5 also excelled in 57% of the bias analyses (PBIAS: -13.436 to 10.188). Regional validation consistently showed more favorable results compared to gauge-based validation. Additionally, data availability significantly influences product accuracy, with stations processing longer records exhibiting superior performance. This study offers valuable insights into the suitability of CHIRPS and ERA 5 hydrological applications in Bodor Sub Watershed, particularly in data-scarce regions. It contributes to improved water resources management strategies.

Abstract

Data curah hujan merupakan data yang sangat penting dalam pengelolaan sumber daya air, sehingga dibutuhkan data curah hujan yang baik, akurat, runtut dan panjang. Namun, ketersediaan data curah hujan di Indonesia masih kurang baik. Persebaran stasiun yang tidak merata, serta banyaknya terjadi kehilangan data, terutama pada daerah-daerah terpencil. Salah satu alternatif untuk menyelesaikan permasalahan kekurangan data tersebut adalah dengan memanfaatkan data dari satelit curah hujan. Dalam menggunakan data curah hujan satelit, harus dilakukan evaluasi terlebih dahulu. Penelitian ini dilakukan untuk mengevaluasi keandalan satelit ERA-5 pada periode bulanan, 15-harian, dan 10-harian di Sub DAS Bodor. Evaluasi dilakukan menggunakan 3 parameter statistik yaitu NSE, RSR, dan r. Hasil evaluasi menunjukkan bahwa satelit ERA-5 memiliki nilai paling andal pada periode bulanan di Sub DAS Bodor (NSE: 0,904; RSR: 0,310; r: 0,952), disusul oleh periode 15-harian (NSE: 0,754; RSR: 0,496; r: 0,875), dan periode 10-harian (NSE: 0,588; RSR: 0,642; r: 0,774).
