MERIS for land applications
In the context of scientific research concerning both global change issues
and regional terrestrial surfaces monitoring, remote sensing products have
been established to be crucial tools to assess the characteristics of both
land surfaces and their temporal evolution.
Advances in the understanding of radiation transfer and availability of
higher performance instruments have lead to the development of a new
generation of geophysical products able to provide reliable, accurate
information on the state and evolution of terrestrial environments.
Specifically, MEdium Resolution Imaging Spectrometer Instrument (MERIS) Level
2 land products are available at both full and reduce resolution.
They include both spectral radiances and geophysical product. The biophysical
values are derived from top of atmosphere radiances using the optimized
Global Vegetation Index (MGVI) algorithm which has been developed to estimate
the Fraction of Absorbed Photosynthetically Active Radiation (FAPAR).After
summarizing the methodology and performance of the MERIS Level 2 products,
this presentation will show the potential the MERIS land products for various
terrestrial applications at both regional and global scale.
