This letter addresses the link availability issue in satellite-based free space optical (FSO) communications. In particular, we present an accurate analysis for estimation of presence clouds and atmospheric turbulence. For this purpose, a meteorological ERA-Interim database, produced by European Center Medium Range Weather Forecast (ECMWF), is investigated. The obtained data is, then, used to a...

Surface incident solar radiation (Rs) is a key parameter in many climatic and ecological processes. The data from satellites and reanalysis have been widely used. However, for reanalysis, Rs data has been shown to have substantial spatial bias, and the time span of reliable satellite Rs is too short for climatic and ecological studies. Combining reanalysis and satellite data would be an effecti...

A new snow scheme for the European Centre for Medium-Range Weather Forecasts (ECMWF) land surface model has been tested and validated. The scheme includes a new parameterization of snow density, incorporating a liquid water reservoir, and revised formulations for the subgrid snow cover fraction and snow albedo. Offline validation (covering a wide range of spatial and temporal scales) includes s...

Long-term global satellite and reanalysis soil moisture products have been available for several years. In this study, in situ soil moisture measurements from 2008 to 2012 over Southwest China are used to evaluate the accuracy of four satellite-based products and one reanalysis soil moisture product. These products are the Advanced Microwave Scanning Radiometer for the Earth observing system (A...

Wind speed affects the navigational safety of Yangtze River, and assessing its spatiotemporal dynamics provides support for navigation management disaster prevention. We developed a wind multiplier downscaling method integrating effects land use topography, used meteorological station observations European Center Medium-Range Weather Forecasts (ECMWF) Reanalysis Interim (ERA-Interim) reanalysis...
