Preparing Fields for the Dynamical Models in HOPS

The packages represent the final stage before running a dynamical model. Data is mapped onto the model domains, freeing the dynamical models from extraneous baggage.


This package takes gridded volume fields and prepares them for insertion into the HOPS PE model as either initialization & boundary condition data or as assimilation fields. Its specific tasks include

  1. Assembly of the objectively analyzed fields with the model grid definitions.
  2. Interpolation of the data from flat analysis levels to terrain following model levels.
  3. Construction of velocity fields via geostrophy. These velocity fields are then vertically interpolated and decomposed into baroclinic and barotropic fields. The determination of the barotropic is particularly sensitive and PE_initial devotes considerable machinery to it.
  4. Scaling of error fields.


This package takes gridded surface flux fields (wind stress, net heat flux, evaporation - precipitation, and shortwave radiation) and interpolates them onto the model grid.
