Measurement of ecosystem metabolism across climatic and vegetation gradients in California for the 2013-2014 NASA AVIRIS/MASTER airborne campaign. The HyspIRI project makes use of flux towers at several of its sites to assess the airborne hyperspectral data. Flux towers measure the exchange of carbon, water and energy between the ecosystem and the atmosphere by collecting …
Scaling of inter- and intra-annual variation in foliar traits derived from imaging spectroscopy A common assumption in remote sensing is that a constituent map made from imagery in one year is representative of constituents in subsequent years. This assumption has been partially supported using ground collected data, but it has never been formally tested using …
Hyperspectral spectroscopy provides the opportunity to estimate key ecosystem traits beyond those derived from traditional remote sensing techniques due to the increased spectral resolution. The HyspIRI project attempts to make measurements of ecosystem metabolism, and we hope to characterize variations in metabolism across a landscape due to climate and species composition. We are using imaging …
