The delay caused by the troposphere is one of major sources errors limiting accuracy InSAR measurements. tropospheric correction measurements important. Weather Research and Forecasting (WRF) Model a state-of-the-art mesoscale numerical weather prediction system designed for atmospheric research applications. It can be applied to correction. Its parameters altered according requirements given a...

Reanalysis temperature products are important datasets for estimates over high-elevation areas with few meteorological stations. In this study, surface 2 m air data from 17 stations 1979 to 2017 in the Qilian Mountains (QLM) used comparison newest reanalysis product: ERA5-Land derived European Centre Medium-Range Weather Forecasts (ECMWF). general, product can reproduce observation variation at...

In recent years, Poland has experienced a significant increase in the installed capacity of solar and wind power plants. Renewables are gaining increasing interest not only because Poland’s obligations to European Union policies, but also they becoming cheaper. Wind energy fairly-well investigated technologies new reports quite frequently added existing research works documenting their potentia...

Abstract. The risk of water erosion on the Tibetan Plateau (TP), a typical fragile ecological area, is increasing with climate change. A rainfall erosivity map useful for understanding spatiotemporal pattern and identifying hot spots soil erosion. This study generates an annual gridded dataset 0.25∘ grid TP in 1950–2020. 1 min precipitation observations at 1787 weather stations 7 years hourly E...

High-resolution meteorological datasets are urgently needed for understanding the hydrological cycle of Tibetan Plateau (TP), where ground-based stations sparse. Rapid advances in remote sensing create possibilities to represent spatiotemporal properties precipitation at a high resolution. In this study, hourly characteristics over TP from two gridded products, one global reanalysis (the fifth ...

This work presents a new dataset for recent climate developed within the Highlander project by dynamically downscaling ERA5 reanalysis, originally available at ?31 km horizontal resolution, to ?2.2 resolution (i.e., convection permitting scale). Dynamical was conducted through COSMO Regional Climate Model (RCM). The temporal of output is hourly (like ERA5). Runs cover whole Italian territory (a...

Abstract There has been a statement that the satellite and reanalyses significantly overestimate snow depths (SDs) as compared with in-situ observations over Tibetan Plateau (TP). The inconsistency may be partly due to representations related different spatial resolutions. To further clarify matters of scale, this work estimates compares fractional cover (FSC) from MODIS (500 m), SDs Sentinel-1...

• Evaluated uncertainty in model soil moisture using TCH and Taylor diagrams over GHA. High levels associated with high rainfall complex terrain. Magnitude of spatial variability contributed higher than patterns. Reanalysis products (ERA5 MERRA2) have lowest uncertainties. Lack situ Greater Horn Africa (GHA) has inhibited evaluation suitability land surface (LSM) and/or satellite-derived the re...

Short-duration rainfall extremes are expected to intensify with warming at around 7%/K, following the Clausius-Clapeyron (CC) relation, causing concomitant increases in flash floods. Observed hourly show consistent CC-scaling dewpoint temperature across all land regions. Here, we use two global climate reanalysis products (ERA5 and MERRA-2) examine consistency scaling observations, ungauged reg...

We use meteorological measurements from three drifting buoys to evaluate the performance of ERA-Interim and ERA5 atmospheric reanalyses European Center for Medium-Range Weather Forecasts over Weddell Sea ice zone. The temporal variability in surface pressure near-surface air temperature is captured well by two but both exhibit a warm bias relative buoy measurements. This small at temperatures c...
