Analysis of Atlantic extratropical storm tracks characteristics in 41 years of ERA5 and CFSR/CFSv2 databases [PDF]

Ocean Engineering, 2020
This work aims to analyze and compare ERA5 and CFSR/CFSv2 from 1979 to 2019 with 1-hourly outputs, regarding their ability to reproduce storm tracks and the main characteristics of cyclones at middle and high latitudes in the North Atlantic (NA) and South Atlantic (SA) Oceans.

CFSR: Coarse-to-Fine High-Speed Motion Scene Reconstruction with Region-Adaptive-Based Spike Distinction

Applied Sciences, 2023
As a novel bio-inspired vision sensor, spike cameras offer significant advantages over conventional cameras with a fixed low sampling rate, recording fast-moving scenes by firing a continuous stream of spikes.

Comparison of Arctic sea ice thickness and snow depth estimates from CFSR with in situ observations [PDF]

Climate Dynamics, 2017
Sea ice growth is modulated by snow cover, and understanding this relationship requires an accurate determination of snow depth. However, a lack of in situ measurements complicates understanding of the interaction of snow depth with sea ice growth. We evaluated the accuracy of Climate Forecast System Reanalysis (CFSR) data for snow depth and sea ice ...

Performance evaluation of CFSR, MERRA-2 and TRMM3B42 data sets in simulating river discharge of data-scarce tropical catchments: a case study of Manafwa, Uganda

Journal of Water and Climate Change, 2022
Data scarcity has been a huge problem in modelling catchments especially in the tropical region. Satellite data and different statistical methods are being used to improve the quality of conventional meteorological data. However, their potential needs to

Evaluation of the performance of CFSR reanalysis data set for estimating reference evapotranspiration (ET0) in Turkey

Italian Journal of Agrometeorology, 2023
Evapotranspiration is a key process and a necessary parameter for hydrological, meteorological, and agricultural studies. However, the calculation of actual evapotranspiration is very challenging and costly. Therefore, reference evapotranspiration (ET0) calculated using meteorological data is generally preferred over actual evapotranspiration. However,

The Asian Subtropical Westerly Jet Stream in CRA-40, ERA5, and CFSR Reanalysis Data: Comparative Assessment

Journal of Meteorological Research, 2021
The Asian subtropical westerly jet (AWJ) exerts crucial influences on Eurasian continent weather and climate. This paper analyzes the advantages and limitations of CRA-40, which is China’s first generation 40-yr (1979–2018) glo-bal atmosphere and land reanalysis product, in describing the characteristics of AWJ, compared with the ECMWF Reanalysis ...

CFSR- NCEP Performance for weather data forecasting in the Pernambuco Semiarid, Brazil

DYNA, 2020
The present study aims to evaluate meteorological data -with real time actualization- from the Climate Forecast System Reanalysis (CFRS) of the National Centers for Environmental Prediction (NCEP), comparing them with data from local stations in two mesoregions: Sertão de Pernambuco (SP) and Sertão do São Francisco (SFF), semi-arid region of Pernambuco,

Assessment of regional best-fit probability density function of annual maximum rainfall using CFSR precipitation data [PDF]

Journal of Earth System Science, 2020
The upper Cross River basin (UCRB) fits a true description of a data scarce watershed in respect of climatic data. This paper seeks to determine the best-fit probability density function (PDF) of annual maximum rainfall for the UCRB using the Climate Forecast System Reanalysis (CFSR) precipitation data.

Evaluation of the Performance of CFSR Reanalysis Data Set for Estimating Potential Evapotranspiration (PET) in Turkey [PDF]

, 2021
Abstract Evapotranspiration is an important parameter for hydrological, meteorological and agricultural studies. However, the calculation of actual evapotranspiration is very challenging and costly. Therefore, Potential Evapotranspiration (PET) is typically calculated using meteorological data to calculate actual evapotranspiration. However, it
