EFAS-Meteo: A European daily high-resolution gridded meteorological data set for 1990 - 2011

Data sets of spatially irregular meteorological observations interpolated to a regular grid are not only important for climate analyses but are also essential in order to derive climatologies for rainfall-runoff models which require meteorological data sets as input forcing. For example, in the European Flood Awareness System long term observed meteorological data are used to drive the hydrological model LISFLOOD to obtain long term time series of simulated discharges at a pan-European scale. Those long term time series of simulated “proxy” discharges can then be used for statistical analysis, e.g., to derive return periods or other time series derivatives. In this report, we present a comprehensive pan European high-resolution gridded daily data set (EFAS-Meteo) of precipitation, surface temperature (mean, minimum and maximum), wind speed, vapour pressure, calculated radiation and evapotranspiration (potential evapotranspiration, bare soil and open water evapotranspiration). The data set was created as part of the development of EFAS and has been continuously updated throughout the last years.JRC.H.7-Climate Risk Managemen

LISVAP Evaporation Pre-Processor for the LISFLOOD Water Balance and Flood Simulation Model

The LISVAP revised User Manual documents the LISVAP application. LISVAP is a pre-processor for the LISFLOOD water balance and flood simulation model that calculates estimates of potential evaporation and evapotranspiration for three separate reference surfaces, all based on the Penman-Monteith equation. The results are reported as raster grids that can be readily used as input to LISFLOOD. The first part of this document describes the characteristics of the LISVAP application in detail, focusing on process descriptions and the governing equations. The second part covers all practical LISVAP issues, such as installing the application, setting up the necessary input data and running it.JRC.H.1-Water Resource
