A general snow accumulation and melt model was developed to (1)determine how accurately snow accumulation and ablation can bemodeled over heterogeneous landscapes with routinely available climatologic, topographic, and vegetation data, and (2) improveestimates of annual forest snow hydrology for point and regionalcalculations of annual forest productivity.(More)
One of the main barriers to exploiting the great wealth of global earth science data available today is that researchers are unable to rapidly search and find data relevant to their studies. This data is spread across a large number of archives maintained by different institutions employing a bewildering array of different data description languages. In(More)
Ecosystem models are used to quantify effccrs of possible climatic and anthropogenic perturbations on biospheric mass and energy fluxcs at regional s d e s (Running 1990; Shugart 1990; Woodward 1990; Wickland 1991). A common modelling strategy is to divide the large study area into homogeneous segments and execute the process model on each segment (Potter(More)
NASA has made science and technology investments to better utilize its large space-borne remote sensing data holdings of the Earth. With the launch of Terra, NASA created a data-rich environment where the challenge is to fully utilize the data collected from EOS however, despite unprecedented amounts of observed data, there is a need for increasing the(More)
