Effects of subpixel water area fraction on mapping leaf area index and modeling net primary productivity in Canada

Retrieving biophysical parameters, such as the leaf area index (LAI) and the net primary productivity (NPP), from remote sensing imagery is very useful for modeling terrestrial ecosystems. Spatial heterogeneity of the land surface often leads to biases in the retrieved parameters when algorithms derived based on high-resolution images are directly used for coarse-resolution images. In the northern environment in Canada, open water bodies are …
