[1] In recent publications, a new basin-scale dataset of monthly variations in terrestrial water storage (BSWB) was derived for the ERA40 time period (1958–2002) using an atmospheric-terrestrial water-balance approach (Seneviratne et al., 2004; Hirschi et al., 2006). Here, we test the feasibility of using ECMWF operational forecast analyses – available for the recent time period in near real ti...

This study makes use of the new Total Column Vater Vapour Data Record (CDR-2 (v2)) —developed by European Space Agency (ESA) in coordination with Satellite Application Facility on Climate Monitoring (CM SAF)— to analyse adequacy integrated vertical water vapour column (IWV) data provided Centre for Medium-Range Weather Forecasts (ECMWF) ERA5 and ERA-Interim reanalyses regions critical interest ...

The European Center for Medium-Range Weather Forecasts (ECMWF) released its latest reanalysis dataset named ERA5 in 2017. To assess the performance of Antarctica, we compare near-surface temperature data from and ERA-Interim with measured 41 weather stations. has a strong linear relationship monthly observations, statistical significant correlation coefficients (p < 0.05) are higher than 0.9...

For more than a decade, the European Centre for Medium-Range Weather Forecasts (ECMWF) has used in-situ observations of 2 m temperature and 2 m relative humidity to operationally constrain the temporal evolution of model soil moisture. These observations are not available everywhere and they are indirectly linked to the state of the surface, so under various circumstances, such as weak radiativ...

This study aims to explore the contrasting characteristics of large-scale circulation that led precipitation anomalies over northern parts Sumatra Island. Further, impact varying Asian–Australian Monsoon (AAM) was investigated for triggering variability area. The moisture budget analysis applied quantify most dominant component induces during JJA (June, July, and August) period. Then, composite...

Despite its fundamental importance in radiative transfer, atmospheric dynamics and the hydrological cycle, atmospheric water is inadequately characterized particularly at a global scale. Occultation measurements from the Global Positioning System (GPS) should imporve upon thids situation. Individual occultations yield profiles of specific humidity accurate to -0.2 gkg providing sensitive measur...
