harmonization.yaml

- specifier: default
  title: Default
  description: >-
    Model should use their individual “best representation” of the historical period
    with regard to sowing dates, harvesting dates, fertilizer application rates and
    crop varieties.

- specifier: fullharm
  title: Fully harmonized
  description: >-
    Simulations based on prescribed “present day” fertilization rates (available for
    download) and fixed planting and harvesting dates (also available for download).
    Modelers should have planting as closely as possible to these dates, but it may
    be admissible to use these dates as indicators for planting windows (depending
    on model specifics).

- specifier: harmnon
  title: Harmonized seasons with no N constraints
  description: >-
    For models with an explicit description of the nitrogen cycle: harmnon simulations
    should be run with nitrogen stress turned off completely or (if that’s not possible)
    with very high N application rates to make model results comparable between those
    GGCMs that have explicit N dynamics and those that do not. For models without
    the nitrogen cycle: harmnon and fullharm simulations are the same and do not need
    to be duplicated. Please contact the sector coordination to push on with this
    side branch.
