Mapping monthly rainfall erosivity in Europe
Rainfall erosivity as a dynamic factor of soil loss by water erosion is modelled intra-annually for the first time at European scale. The development of Rainfall Erosivity Database at European Scale (REDES) and its 2015 update with the extension to monthly component allowed to develop monthly and seasonal R-factor maps and assess rainfall erosivity both spatially and temporally. During winter m...
متن کاملEstimation of monthly-mean daily global solar radiation based on MODIS and TRMM products
0306-2619/$ see front matter 2011 Elsevier Ltd A doi:10.1016/j.apenergy.2011.01.018 ⇑ Corresponding author. E-mail address: [email protected] (J. Qin). Global solar radiation (GSR) is required in a large number of fields. Many parameterization schemes are developed to estimate it using routinely measured meteorological variables, since GSR is directly measured at a limited number of station...
متن کاملImproving Rainfall Erosivity Estimates Using Merged TRMM and Gauge Data
Soil erosion is a global issue that threatens food security and causes environmental degradation. Management of water erosion requires accurate estimates of the spatial and temporal variations in the erosive power of rainfall (erosivity). Rainfall erosivity can be estimated from rain gauge stations and satellites. However, the time series rainfall data that has a high temporal resolution are of...
متن کاملMonthly Rainfall Erosivity: Conversion Factors for Different Time Resolutions and Regional Assessments
As a follow up and an advancement of the recently published Rainfall Erosivity Database at European Scale (REDES) and the respective mean annual R-factor map, the monthly aspect of rainfall erosivity has been added to REDES. Rainfall erosivity is crucial to be considered at a monthly resolution, for the optimization of land management (seasonal variation of vegetation cover and agricultural sup...
متن کاملCalibration and Testing of a Daily Rainfall Erosivity Model
A general procedure is presented for calibrating a model for rainfall erosivity based on daily rainfall. The approach is based on probability distributions of wet-day precipitation amount and monthly erosivities which are inferred from published data summaries. The calibrated model was tested by comparisons with erosivities computed from hourly precipitation data. Model results were generally c...
