ERA-Interim/Land: a global land surface reanalysis data set
ERA-Interim/Land is a global land surface reanalysis data set covering the period 1979–2010. It describes the evolution of soil moisture, soil temperature and snowpack. ERA-Interim/Land is the result of a single 32-year simulation with the latest ECMWF (European Centre for MediumRange Weather Forecasts) land surface model driven by meteorological forcing from the ERA-Interim atmospheric reanaly...
متن کاملDevelopment of a global land cover characteristics database and IGBP DISCover from 1 km AVHRR data
Researchers from the U.S. Geological Survey, University of Nebraska– Lincoln and the European Commission’s Joint Research Centre, Ispra, Italy produced a 1 km resolution global land cover characteristics database for use in a wide range of continentalto global-scale environmental studies. This database provides a unique view of the broad patterns of the biogeographical and ecoclimatic diversity...
متن کاملCharacterizing land surface anisotropy from AVHRR data at a global scale using high performance computing
We used the multi-temporal ten-day composite data from the Advanced Very High Resolution Radiometer (AVHRR) for the years 1983 to 1986 to retrieve the Bidirectional Re ectance Distribution Function (BRDF ) using high performance computing techniques. Three diVerent models are used: a simple linear model, a semi-empirical iterative model and a temporal model. The objectives of this study were t...
متن کاملSeasonality of Pathfinder Avhrr Land Ndvi Data for Northeastern Brazil
The Normalized Difference Vegetation Index (NDVI) was used to characterize the seasonal variation of land cover over the Northeastern Brazil (NEB) with the NOAA/NASA Pathfinder AVHRR Land (PAL) data set. Twenty years of monthly spatial-aggregated NDVI climatology was determined by calculating lower, mean, and upper NDVI values using a 0.5 lat by 0.5 log grid cell size. The results indicated tha...
متن کاملLand-cover classi cation methods for multi-year AVHRR data
AdvancedVery HighResolutionRadiometer (AVHRR) data have been extensively used for global land-cover classi cation, but few studies have taken direct and full advantage of the multi-year properties of AVHRR data. This study focused on generating eVective classi cation features from multi-year AVHRR data to improve classi cation accuracy.Three types of features were derived from 12-year monthl...
