BigFoot data

BigFoot is designed to provide the spatial context of flux towers using a combination of in situ ecological data, Landsat ETM+ data, and ecosystem models. Moreover, BigFoot maps land cover, LAI, fraction absorbed photosynthetic active radiation, and NPP over a 5 x 5 km area around an eddy flux tower at ETM+ resolution. They fully characterize 25 MODIS cells around a given tower site, and are able to test a number of scaling factors that should reveal possible causes of MODIS mapping errors (thereby providing feedback to algorithm developers). Finally, BigFoot takes important steps to enhance the goals of GTOS. There are nine BigFoot study sites that span eight major biomes, from desert to tundra, to tropical forest. The BigFoot project collects data and generates products at several scales of measurement. Selected results are presented visually in map and graphic galleries organized by study site.
