In the study, performance of MIKE 21 SW (Spectral Wave) model using three different wind fields, namely ERA-Interim, ERA5, and CFSR was evaluated in Eastern Mediterranean Sea. Model results were calibrated with four buoy measurements by tuning physical parameters. Wave simulations showed a strong sensitivity to whitecapping parameter (Cds). Calibrated run validate at two measurements. Consideri...

The Arctic has experienced large climate changes over recent decades, the largest for any region on Earth. To understand the underlying reasons for this climate sensitivity, reanalysis is an invaluable tool. The Arctic System Reanalysis (ASR) is a regional reanalysis, forced by ERA-Interim at the lateral boundaries and incorporating model physics adapted to Arctic conditions, developed to serve...

18 The interannual variability of cloud properties in a tropical subsidence area (South 19 Atlantic Ocean) is examined using 23 years of ISCCP cloud fractions and optical depths, 20 complemented with ISCCP/Meteosat visible reflectance and a four-years comparison with 21 CALIPSO-GOCCP products. The mean seasonal cloud properties are examined in the area, as 22 their interannual evolution. Circul...

[1] Ground-based GPS measurements can provide independent data for the assessment of climate models. We use the atmospheric integrated water vapor (IWV) obtained from GPS measurements at 99 European sites to evaluate the regional Rossby Centre Atmospheric climate model (RCA) driven at the boundaries by the European Centre for Medium-Range Weather Forecasts (ECMWF) reanalysis data (ERA Interim)....

It is well known from previous research that significant differences exist amongst reanalysis products from different institutions. Here, we compare the skill of NCEP-R (reanalyses by the National Centers for Environmental Prediction, NCEP), ERA-int (the European Centre of Medium-range Weather Forecasts Interim), JCDAS (the Japanese Meteorological Agency Climate Data Assimilation System reanaly...

Abstract Surface incident solar radiation ( R s ) is important for providing essential information on climate change. Existing studies have shown that the values from current reanalyses are significantly overestimated throughout China. The European Centre Medium-Range Weather Forecasts (ECMWF) recently released fifth generation of atmospheric reanalysis (i.e., ERA5) with a much higher spatiotem...

The Mediterranean region is characterized by its vulnerability to changes in the water cycle, with the impact of global warming on the water resources being one of the major concerns in social, economical and scientific ambits. Even if precipitation is the best-known term of the Mediterranean water budget, large uncertainties remain due to the lack of suitable offshore observational data. In th...

High resolution information of climatic conditions is essential to many application in environmental sciences. Here we present the CHELSA algorithm to downscale temperature and precipitation estimates from the European Centre for Medium-Range Weather Forecast (ECMWF) climatic reanalysis interim (ERA-Interim) to a high resolution of 30 arc sec. The algorithm for temperature is based on a statist...
