ACCP

In the autumn of 1991, the High Resolution Imaging Spectrometer (HIRIS) was de-selected for NASA's Earth Observing System (EOS) program. However, the EOS Investigator Working Group (IWG) had determined that the potential for high spectral resolution remote sensing to estimate nitrogen and lignin concentrations in vegetative canopies, and from these, rates of ecosystem function, was not addressed by other EOS instruments. So, the HIRIS Science Team used its remaining funding to clarify the scientific validity of this application, forming the Accelerated Canopy Chemistry Program (ACCP).
