The frequency and severity of forest fires, coupled with changes in spatial and temporal precipitation and temperature patterns, are likely to severely affect the characteristics of forest and permafrost patterns in boreal eco-regions. Forest fires, however, are also an ecological factor in how forest ecosystems form and function, as they affect the rate and characteristics of tree recruitment....

The major physiological processes of vegetation including photosynthesis and evapotranspiration are determined by the vegetation biophysical parameters that describe the canopy structure. Leaf area index (LAI) is one of the principal biophysical parameters in climate, weather, and ecological studies, and has been routinely estimated from remote sensing measurements. LAI is defined as one half t...

There are significant issues and problems in the integration of remotely sensed data and GIS due to the differences in data characterisation, data structure and data processing philosophy between the two technologies. Difficulties exist particularly in handling large data volumes in GIS which are unavoidable when using remotely sensed imagery. This paper focuses on the integration of image data...

The unavailability of thermal infrared satellite observations in cloudy conditions has limited the spatial distribution and temporal coverage remotely sensed evapotranspiration (ET) data. As a result, number approaches have been developed to reconstruct daily ET data cloudy-sky conditions. Despite wide application these approaches, no work conducted compare their performance over variety climat...
