Product Global 3D ecosystem model results (see table below for NetCDF files)

These files are from year 24 from a simulation initialized with climatological nutrients and a best guess for iron initial conditions as described in Moore et al (2004). Relevant parameter values and physical forcing can also be found in this reference. Please cite Moore et al (2004) for any use of this data and also please let him know about your research (or any questions) by sending an email to

Model results reported as twelve monthly files (NetCDF):

Scalar variables in this simulation include:

Variable Name Variable description/definition

diatFediatom iron
diazCdiazotroph carbon
diazChldiazotroph Chlorophyll
diazFediazotroph iron
DONdissolved organic nitrogen
DOFedissolved organic iron
DOPdissolved organic phosphorus

Fluxes between compartments are included in the results, as are various other diagnostic fields. IMPORTANT NOTE: Air-sea gas exchange is computed, but this data should not be used as virtual fluxes were not correctly accounted for in this simulation. Diagnostics indicated by a _lim suffix indicate the computed growth limitation based on the ambient available quantity (value 0-1) (e.g. sp_N_lim is the nitrogen limitation factor for small phytoplankton). The maximum growth rates are multiplied by the appropriate minimum nutrient limitation factor and by the light limitation factor to compute actual growth rates.
