Stochastic Post-Processing of CFSR Daily Precipitation across Canada

Atmosphere-Ocean, 2018
[Traduit par la redaction] Les reanalyses, fondees sur des methodes de prevision numerique du temps qui assimilent les observations existantes, fournissent des champs continus de donnees de precipitations et representent une option interessante pour evaluer la climatologie des regions ou les stations de mesures restent rares (p. ex., le nord du Canada).

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- 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,

CMADS and CFSR Data-Driven SWAT Modeling for Impacts of Climate and Land-Use Change on Runoff

Water, 2023
Climate and land-use change significantly impact hydrological processes and water resources management. However, studies of runoff simulation accuracy and attribution analysis in large-scale basins based on multi-source data and different scenario projections are limited.

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.

Daily Precipitation Fields Modeling across the Great Lakes Region (Canada) by Using the CFSR Reanalysis

Journal of Applied Meteorology and Climatology, 2018
AbstractReanalyses, generated by numerical weather prediction methods assimilating past observations, provide consistent and continuous meteorological fields for a specific period. In regard to precipitation, reanalyses cannot be used as a climate proxy of the observed precipitation, as biases and scale mismatches exist between the datasets.

Regional modeling of daily precipitation fields across the Great Lakes region (Canada) using the CFSR reanalysis

Stochastic Environmental Research and Risk Assessment, 2019
High densities of local-scale daily precipitation series across relatively large domains are of special interest for a wide range of applications (e.g., hydrological modeling, agriculture). The focus of the present study is to post-process gridded precipitation from a single reanalysis to correct bias and scale mismatch with observations, and to extend

Simulation of water cycle components in the Narmada River basin by forcing SWAT model with CFSR data

Meteorology Hydrology and Water Management, 2017
In the present study, an attempt has been made through a hydrological model (SWAT – Soil and Water Assessment Tool) to simulate water cycle components over the Narmada river basin, one of the largest rivers in the Indian peninsula.

Diurnal variability of water vapour in the Baltic Sea region according to NCEP-CFSR and BaltAn65+ reanalyses

Oceanologia, 2014
Diurnal variations in water vapour in the Baltic Sea region are examined using BaltAn65+ and NCEP-CFSR reanalyses of summer (JJA) data for the period 1979-2005. A systematic difference between precipitable water (PW) diurnal variability above the land and the water is revealed. Above the land, PW diurnal variability has minimal values at 00 and 06 UTC,

Impact of the Ensemble Kalman Filter Based Coupled Data Assimilation System on Seasonal Prediction of Indian Summer Monsoon Rainfall

Geophysical Research Letters, 2022
The sensitivity of seasonal prediction (June to September) of Indian monsoon to initial state from two variants of coupled data assimilation (CDA) products, viz.
