RAMI V phase

2020 - on going


  1. October 2020 - November 2021
    Active submission period
  2. January 2022
    On-line results

The new RAMI phase is now open: RAMI V is a continuation of previous phases of RAMI but due to the availability of the RAMI On-line Model Checker (ROMC) all canopy scenes were newly designed for RAMI V.

More specifically, in RAMI V different types of plant environments are available:

  • Abstract canopies, contain both homogeneous (HOM) and heterogeneous (HET) leaf canopies that are both exclusively composed of disc-shaped finite-sized scatterers. These test cases are all based upon similar experiments from previous phases of RAMI. Note, however, that the number of the standardised measurements differs between the HOM and HET canopy scenes;
  • Actual canopies, are reconstructed from detailed inventories of both the structural and spectral properties of existing plantations and forest stands. Canopy descriptions therefore contain a large amount of statistics that should allow different types of test cases to implement the stand architectures and to generate a variety of radiative quantities in multiple spectral bands in the solar domain (as well as under conservative scattering conditions). Note, that the number of predefined measurements differs between the forest and plantation scenes;
  • Savanna scene, models of a two-layer savanna heterogeneous system were established including an over-storey (tree) and an under-storey (grass) layer;
  • Wytham Wood, a one hectare model for a deciduous forest in Wytham, UK;

Access to the various experiment description pages can be obtained from the "Scenes" and/or "Measurements" options in the above menu.
