چکیده | ||
برآورد قابل اعتماد بارش یکی از ضروریترین نیازها در مدیریت منابع آب است. با این حال، در بسیاری از نقاط جهان، به ویژه ایران کمبود زمانی و مکانی دادههای بارش بسیار محسوس است. لذا استفاده از اطلاعات ماهوارهای یکی از راهکارهای جبران کمبود اطلاعات میباشد. هدف از این پژوهش، مقایسه دقت اطلاعات بارش دو محصول TRMM-3B42 و PERSIANN-CDR در مقیاس روزانه است. محصولات این دو ماهواره بصورت رایگان در پیکسل سایز ۰.۲۵ درجه و روزانه در دسترس است. برای اینکار از بارندگی روزانه 12 ایستگاه در دامنههای جنوبی البرز در یک دوره آماری 2014-2000 استفاده شد. نتایج نشان ارجحیت این دو محصول ماهواره ای در پارامترهای آماری مختلف یکسان نیست، بطوریکه CDR و 3B42 به ترتیب 100% و 25% تعداد وقایع بارش را بیشتر از ایستگاهها برآورد کرده اند. همچنین ماهواره PERSIANN نسبت به 3B42 بطور قابل توجهی از نظر پارامتر های RMSE, POD و CSI برتری دارد ولی در مقابل از نظر پارامتر های Bias و FAR ضعیفتر است. لذا انتخاب محصول ماهواره ای مورد نظر باید بر اساس پارامتر مورد توجه صورت گیرد. | ||

چکیده [English] | ||
Reliable estimation of precipitation is one of the most essential needs in water resources management. However, in many parts of the world, especially in Iran, the lack of time and place of rainfall data is very noticeable. Therefore, the use of satellite information is one of the ways to compensate for the lack of information. The purpose of this research is to compare the accuracy of rainfall information of TRMM-3B42 and PERSIANN-CDR products on a daily scale. The products of these two satellites are available daily for free in the pixel size of 0.25 degrees. The daily rainfall of 12 stations in the southern slopes of Alborz in a statistical period of 2000-2014 was used. The results show that these two satellite products are not the same in different statistical parameters, so that CDR and 3B42 have estimated 100% and 25% more rainfall events than the stations, respectively. Also, PERSIANN satellite is significantly superior to 3B42 in terms of RMSE, POD and CSI parameters, but on the other hand, it is weaker in terms of Bias and FAR parameters. Therefore, the selection of the desired satellite product should be based on the proper parameters. | ||
