AVIRIS performance during the 1987 flight season: An AVIRIS project assessment and summary of the NASA-sponsored performance evaluation

摘要: Results are presented of the assessment AVIRIS performance during 1987 flight season by project and earth scientists who were chartered NASA to conduct an independent data quality sensor evaluation. The evaluation program began in late June with meeting most its design requirements except for signal-to-noise ratio fourth spectrometer, which was about half required level. Several events related parts failures flaws further reduced over season. Substantial agreement found between assessments investigators effects these various factors. A summary engineering work that is being done raise level given. In spite degrading season, several exciting scientific results obtained from data. These include mapping spatial variation atmospheric precipitable water, detection environmentally-induced shifts spectral red edge stressed vegetation, features pigment, leaf water ligno-cellulose absorptions plants, identification many diagnostic mineral absorption a variety geological settings.
