Last change on this file since 5301 was 2665, checked in by dcugnet, 8 years ago
  • A (re)startphy.nc file (standard name: "startphy0.nc") can be read by ce0l to get land mask, so mask can be defined (in decreasing priority order) from: 1) "o2a.nc file" if this file is found 2) "startphy0.nc" if this file is found 3) "Relief.nc" otherwise
  • Sub-cell scales parameters for orographic gravity waves can be read from file "oro_params.nc" if the configuration key "read_orop" is TRUE. The effect is to bypass the "grid_noro" routine in ce0l, so that any pre-defined mask (from o2a.nc or startphy0.nc) is then overwritten.
  • The gcm stops if the "limit.nc" records number differs from the current year number of days. A warning is issued in case the gcm calendar does not match the time axis attribute "calendar" (if available) from the "limit.nc" file. This attribute is now added to the "limit.nc" time axis.
  • Few simplifications in grid_noro
  • Few parameters changes in acama_gwd and flott_gwd.
  • Variable d_u can be saved in the outputs.

4! Purpose: Initial states and boundary conditions files creation:
5!     * start.nc    for dynamics    (using etat0dyn     routine)
6!     * startphy.nc for physics     (using etat0phys    routine)
7!     * limit.nc    for forced runs (using limit_netcdf routine)
8!-------------------------------------------------------------------------------
9! Notes:
10!     * extrap=.T. (default) for data extrapolation, like for the SSTs when file
11!                   does contain ocean points only.
12!     * "masque" can be:
13!       - read from file "o2a.nc"          (for coupled runs).
14!       - read from file "startphy0.nc"    (from a previous run).
15!       - created in etat0phys or etat0dyn (for forced  runs).
16!     It is then passed to limit_netcdf to ensure consistancy.
