摘要: ERA-Interim/Land is a global land surface reanalysis data set covering the period 1979–2010. It describes evolution of soil moisture, temperature and snowpack. result single 32-year simulation with latest ECMWF (European Centre for Medium-Range Weather Forecasts) model driven by meteorological forcing from ERA-Interim atmospheric precipitation adjustments based on monthly GPCP v2.1 (Global Precipitation Climatology Project). The horizontal resolution about 80 km time frequency 3-hourly. includes number parameterization improvements in scheme respect to original set, which makes it more suitable climate studies involving water resources. quality assessed comparing ground-based remote sensing observations. In particular, estimates snow depth, albedo, turbulent latent sensible fluxes, river discharges are verified against large site measurements. provides integrated coherent estimate moisture equivalent, can also be used initialization numerical weather prediction models.
