To understand the spectral properties associated with various vegetation types and responses to stress agents, appropriate ground-based analytical techniques must document botanically significant spectral information that can be detected from sensors such as TM. This paper describes a NASA-sponsored study in progress at the Jet Propulsion Laboratory (JPL) and Goddard Space Flight Center (GSFC) that uses data from intensive ground assessments in conjunction with aircraft overflights. In this study, the authors have used an aircraft multispectral scanner known as the thematic mapper simulator (TMS) to duplicate TM spectral coverage of study sites. In addition, helicopter-mounted radiometers duplicating TM coverage have permitted multiple sampling of single sites. They also coordinated simultaneous ground-based surveys to improve their understanding of site variables and spectral characteristics associated with forest decline sites. Ground assessment included in situ spectral analysis as well as determination of physiological status and anatomical/morphological conditions associated with forest species in various stages of decline.
