اندازه گیری های دقیق بارندگی درانواع مقیاس های مکانی و زمانی نه تنها برای پیش بینی وضع هوا و علوم اقلیمی بلکه برای گستره وسیعی از مدیریت ها از جمله آبشناسان، کشاورزان، مدیریت های بحران، و صنعتگران دارای اهمیت بالایی می باشد. با این حال، درکاربردهای مذکورکمبود صحت دیده بانی های بارندگی در نواحی دور و در حال توسعه جوامع را با چالش مهمی روبه رو کرده است. در بسیاری از کشورهای جهان سوم شبکه های دیده...
This study investigates the applicability of Satellite Precipitation Products (SPPs) in near real-time for simulation sub-daily runoff Vilcanota River basin, located southeastern Andes Peru. The data from rain gauge stations are used to evaluate quality Integrated Multi-satellite Retrievals GPM–Early (IMERG-E), Global Mapping Precipitation–Near Real-Time (GSMaP-NRT), Climate Prediction Center M...
Evaluation of rainfall retrievals from SEVIRI reflectances over West Africa using TRMM-PR and CMORPH
Hydrological modeling has always been a challenge in the data-scarce watershed, especially areas with complex terrain conditions like inland river basin Central Asia. Taking Bosten Lake Basin Northwest China as an example, accuracy and hydrological applicability of satellite-based precipitation datasets were evaluated. The gauge-adjusted version six widely used was adopted; namely, Precipitatio...
In order to measure precipitation as the main variable for estimating the runoff and designing hydraulic structures, the satellite algorithm products that have the proper spatial and temporal coverage, can be used. In this study, at first, the daily streamflow simulation of Sarough-Cahy River from the Zarinehroud basin was conducted through the artificial neural network (ANN) and ground data of...
The number of global precipitation datasets (PPs) is on the rise and they are commonly used for hydrological applications. A comprehensive evaluation their performance in modeling required to improve performance. This study comprehensively evaluates eight widely PPs by comparing with gauge-observed a large catchments. These include Global Precipitation Climatology Centre (GPCC), Climate Hazards...
