%  Build a ROMS climatology file
%
%  Extrapole and interpole temperature and salinity from a
%  Climatology to get boundary and initial conditions for
%  ROMS (climatology and initial netcdf files) .
%  Get data from ORCA 05 climatology
%
%  Data input format (netcdf):
%     temperature(T, Z, Y, X)
%     T : time [Months]
%     Z : Depth [m]
%     Y : Latitude [degree north]
