This paper presents a validation of atmospheric reanalysis data sets for simulating onshore wind generation time series large-scale energy system studies. The three reanalyses are the ERA5, New European Wind Atlas (NEWA) and DTU’s previous European-level (EIWR). An optional scaling is applied to match microscale mean speeds reported in Global version 2 (GWA2). speed used account effects terrain...

Many extreme meteorological events are closely related to the strength of land–atmosphere interactions. In this study, heat exchange regime between shallow soil layer and atmosphere over Qinghai–Tibetan Plateau (QTP) was investigated using a reanalysis dataset. The analysis conducted simple metric ΔT, defined as difference temperatures air. First, performance 4 widely used data products (GLDAS-...

BACKGROUND: Epidemiological analyses of health risks associated with non-optimal temperature are traditionally based on ground observations from weather stations. Though generally considered representative the actual ambient conditions and individual’s exposure, their broader application in environmental epidemiology is often constrained by inhomogeneous records sparse density meteorological Cl...

Atmospheric circulation is a key driver of climate variability, and the representation atmospheric modes in regional models (RCMs) can enhance credibility projections. This study examines large-scale Coupled Model Inter-comparison Project phase 5 RCMs once driven by ERA-Interim, two general (GCMs). The region Western Europe are classified using Promax rotated T-mode principal component analysis...

Abstract. Rain-on-snow (ROS) events can accelerate the surface ablation of sea ice, thus greatly influencing ice–albedo feedback. However, variability ROS over Arctic Ocean is poorly understood due to limited historical station data in this region. In study early melt season were investigated based on four widely used reanalysis products (ERA-Interim, JRA-55, MERRA, and ERA5) conjunction with a...

Abstract This study evaluates snow depth (SD) from several data sources: a combined satellite-based and in situ water equivalent product the Copernicus Global Land Service (CGLS), dataset constructed temperature, precipitation, relative humidity using model (CARPATCLIM), two state-of-the-art reanalyses by ECMWF (ERA5 ERA5-Land), Weather Research Forecasting (WRF) regional climate simulations at...

Abstract. The stratospheric Brewer–Dobson circulation (BDC) is an important element of climate as it determines the transport and distributions key radiatively active atmospheric trace gases, which affect Earth's radiation budget surface climate. Here, we evaluate interannual variability, climatology, trends BDC in ERA5 reanalysis intercompare them with its predecessor, ERA-Interim reanalysis, ...

Sea surface temperature (SST) is a key factor for both climate and weather. Most studies focus on evaluation of satellite SSTs in different oceanic regions, but the performance ERA5 reanalysis SST datasets (ERA5 SSTs) has not been systematically evaluated. In this article, buoy measurements from 46 National Data Buoy Center (NDBC) sites around Pacific Atlantic are used to make an analysis devia...
