Plant functional type classification for earth system models:results from the European Space Agency's Land Cover Climate Change Initiative
Plant functional type classification earth system models European Space Agency Land Cover Climate Change Initiative
2015/8/6
Global land cover is a key variable in the earth system with feedbacks on climate, biodiversity and natural resources. However, global land cover data sets presently fall short of user needs in provid...
PRACTISE – Photo Rectification And ClassificaTIon SoftwarE (V.1.0)
PRACTISE Photo Rectification ClassificaTIon SoftwarE
2014/12/12
Terrestrial photography is a cost-effective and easy-to-use method for measuring and monitoring spatially distributed land surface variables. It can be used to continuously investigate remote and ofte...
Characterization and Classification of Rocks with Lamb Modes
Ultrasound Lamb Waves Nondestructive Investigation
2013/3/8
The nondestructive investigation by ultrasound has become a fundamental tool for characterizing rocks. We applied this technique for characterizing samples of rocks. The later had been members of the ...
Statistical Evaluation of Classification Diagrams for Altered Igneous Rocks
TAS classification volcanic rocks plutonic rocks chemical classification correct statistical analysis of compositional data
2010/10/14
The International Union of Geological Sciences (IUGS) has proposed recommendations for the classification of relatively fresh volcanic rocks, but with no specific instructions for altered volcanic roc...
Dual-polarization C-band weather radar algorithms for rain rate estimation and hydrometeor classification in an alpine region
Dual-polarization C-band weather rain rate
2010/2/3
Dual polarization is becoming the standard for new weather radar systems. In contrast to conventional weather radars, where the reflectivity is measured in one polarization plane only, a dual polariza...
Hydrometeor classification from dual-polarized weather radar: extending fuzzy logic from S-band to C-band data
Hydrometeor classification dual-polarized weather
2010/1/27
A model-based fuzzy classification method for C-band polarimetric radar data, named Fuzzy Radar Algorithm for Hydrometeor Classification at C-band (FRAHCC), is presented. Membership functions are desi...
Comparison of pattern-recognition techniques for classification of Silurian rocks from Lithuania based on geochemical data
pattern-recognition techniques classification Silurian rocks geochemical data
2009/12/3
There is no widely recognized chemical classification of sedimentary rocks. The geochemical classification of sedimentary rocks utilizes features that can be observed in hand specimens or in thin sect...
Automatic regional classification of topography in Norway
Automatic regional classification topography Norway
2009/12/2
The objective of this study is to apply a combined region-growing and classification method for a first automatic landform segmentation of Norway at a regional scale. The classification is based on pr...
First results on a process-oriented rain area classification technique using Meteosat Second Generation SEVIRI nighttime data
a process-oriented rain area classification technique Meteosat Second Generation SEVIRI nighttime data
2010/1/28
A new technique for process-oriented rain area classification using Meteosat Second Generation SEVIRI nighttime data is introduced. It is based on a combination of the Advective Convective Technique (...
Precipitation classification at mid-latitudes in terms of drop size distribution parameters
Precipitation classification drop size distribution parameters
2010/1/28
The drop size distribution (DSD) is a fundamental property of rainfall because the shape of the distribution reflects the physics of rain formation processes. Given the lack of studies on the DSD at m...
Multiple steady-states in the terrestrial atmosphere-biosphere system:a result of a discrete vegetation classification?
Multiple steady-states atmosphere-biosphere system discrete vegetation classification
2010/1/14
Multiple steady states in the atmosphere-biosphere system can arise as a consequence of interactions and positive feedbacks. While atmospheric conditions affect vegetation productivity in terms of ava...
Analysis of the suitability of the German soil texture classification for the regional scale application of physical based hydrological model
the German soil texture classification the regional scale application hydrological model
2010/1/27
Regional scale hydrological simulations are mostly based on the use of standard data sets such as soil maps which are based on soil texture classification schemes. This paper analyses the suitability ...
A methodology for the classification of convective structures using meteorological radar:Application to heavy rainfall events on the Mediterranean coast of the Iberian Peninsula
convective structures meteorological radar heavy rainfall event Mediterranean coast
2009/12/16
During the period 1996–2000, forty-three heavy rainfall events have been detected in the Internal Basins of Catalonia (Northeastern of Spain). Most of these events caused floods and serious damage. Th...
