Aquatic and terrestrial optical measurements - laser induced fluorescence technique (ATOM-LIFT): Summer 1997 field measurement campaign

摘要

A joint IROE-CNR, NASA/GSFC, and USDA/ARS measurement campaign was conducted in Italy for a three week period in July, 1997. The campaign was split into two parts: the first part for aquatic vegetation studies and the second part for terrestrial vegetation studies. The main objective of the campaign was to study optical properties of intact plant material as it relates to photosynthetic activity of living vegetation. The aquatic studies were carried out at an aquarium-laboratory in the seashore city of Livorno on the West coast of Italy. The investigations involved an important sea grass species that is native to the Mediterranean Sea. The terrestrial studies were carried out Northeast of the Town of St. Stefano di Cadore (Belluno), Italy. Measurements were taken in a wooded site at an Italian Department of Forestry Station on species of natural alpine vegetation. Instrumentation available for the studies were the Italian Fluorescence Light Detection And Ranging (FLIDAR) System, the NASA/USDA Fluorescence Imaging System (FIS), the Perkin Elmer Spectrofluorometer and LI-COR 6400 infrared gas exchange analyzer for photosynthesis measurements. Preliminary evaluations, analysis, and summaries were made by personnel from both Italian and United Sates groups on data collected during the measurement campaign. The joint Italian/American data collection effort with Aquatic and Terrestrial Optical Measurements produced a range of data for characterizing the relationships between fluorescence and the photosynthetic potentials of vegetative scenes.
