This article reviews state-of-the-art algorithms for estimating land surface biogeophysical variables in optical remote sensing (from the visible to the thermal infrared spectrum) to stimulate the development of new algorithms and to utilize
Use of terrain variables for mapping gully erosion susceptibility in Lebanon
This paper predicts the geographic distribution and size of gullies across central Lebanon using a geographic information system (GIS) and terrain analysis. Eleven primary and three secondary topographic variables were generated and used along
with digital data collected from other sources (soil, geology) to statistically explain gully erosion field measurements. Three tree-based regression models were developed using different variables. The best regression tree model combined the steady-state
topographic wetness and sediment transport capacity indices and explained 80% of the variability in field gully measurements.
Traditional and geographic box plots of one hypothetical and two real-world geographic variables are constructed and compared to illustrate the often marked differences between traditional and geographic box plots of the same geographic variables
. The real-world geographic variables considered here are human population density (in the year 2000) within the contiguous 48 United States and five-year-average (January 2001 - December 2005) air temperature over the Artic land surface. Discussion
This paper studies the change of streamflow and the impact of climatic variability conditions on regional hydrological cycle in the headwater of the Tarim River Basin. This study investigates possible causes of observed trends in streamflow
in an environment which is highly variable in terms of atmospheric conditions, and where snow and ice melt play an important role in the natural hydrological regime.

This study investigates relationships among land use, overall vegetation production, and climate variability in Shaanxi Province between 2000 and 2004. The data in this assessment include remote sensing information from moderate-resolution imaging
Regional variability of volcanic ash soils in south Ecuador : the relation with parent material, climate and land use
In this high Andes region, the land use changes affect particularly the páramo. The AA. analyse the regional variability of the soils in the south Ecuadorian rio Paute basin. Data from soil profiles along north-south transects are used to determine
the soil properties, and to relate the spatial variability of these properties to the major trends in parent material, volcanic ash deposits and climate. The impact of human activities on the soil properties is assessed in a case study in the Machangara

With a variable or changing climate, short-term energy imbalances between the active layer and permafrost result in transient departures from the equilibrium condition. This study examines the effects of such variability on an equilibrium permafrost
