Validation of ERA-Interim Precipitation Estimates over the Baltic Sea
European Centre for Medium-Range Weather Forecasts (ECMWF) ERA-Interim reanalysis total precipitation estimates are validated against ten years of in situ precipitation measurements onboard of ships over the Baltic Sea. A statistical analysis for binary forecasts and mean rain rates derived from all data show a good agreement with observations. However, a closer look reveals an underestimation ...
متن کاملمقایسة مجموعه دادههای ERA5 و ERA-Interim در محاسبة تغییرات جرم کوتاهمدت جوی و اثرات آن بر ارتفاع ژئویید
میدان گرانی حاصل از مشاهدات گرانیسنجی ماهوارهای مانند GRACE شامل خطاهایی ناشی از نوفة دستگاهی، نمونهبرداری مکانی ناهمسانگرد (anisotropic) و خطای تداخل سیگنال (aliasing) و زمانی ناشی از نقص مدلسازی تغییرات جرم کوتاهمدت زمین است. کیفیت مشاهدات GRACE در مأموریت GRACE-FO بهبود یافت، اما خطای تداخل سیگنال زمانی همچنان یک عامل تأثیرگذار بر گرانی محاسباتی از مشاهدات میباشد. به همین دلیل محاسبه ...
متن کاملGlobal wave model validation using ENVISAT ASAR wave mode data
Spaceborne active radar remote sensing, e.g., radar altimeter (RA) and synthetic aperture radar (SAR) have been playing an important role in the validation of numerical wave models, particularly in open ocean. Most forecast centres also use altimeter data in the wave data assimilation process. In this paper we present validation results based on the newly developed CWAVE_ENV algorithm. SAR wave...
متن کاملERA-Interim/Land: a global land surface reanalysis data set
ERA-Interim/Land is a global land surface reanalysis data set covering the period 1979–2010. It describes the evolution of soil moisture, soil temperature and snowpack. ERA-Interim/Land is the result of a single 32-year simulation with the latest ECMWF (European Centre for MediumRange Weather Forecasts) land surface model driven by meteorological forcing from the ERA-Interim atmospheric reanaly...
متن کاملThe Global Validation of Ers Wind and Wave Products at Ecmwf
Since the beginning of the ERS-1 mission, ECMWF is involved in the global validation and long-term performance monitoring of the wind and wave Fast Delivery products that are retrieved from the Radar Altimeter (RA), the Synthetic Aperture Radar (SAR) and the Active Microwave Instrument (AMI), on-board the ERS spacecrafts. Their geophysical content is compared with corresponding parameters from ...
