SUBGRID : to define parameters of an ALADIN subgrid (1999)

1999

This procedure defines the two corners (SW and NE) of a subgrid Aladin, given :

  • the native grid parameters,
  • the approximative SW subgrid corner (in degrees) : ZLONU & ZLATU
  • the number of points of the subgrid (for C+I) : IDLUXU & IDGUXU

The files location is on andante: /u/mrpm/mrpm602/subgrid

example : see namelist namex and run "subgrid namex"
Alternatively, if the namelist parameter LLDIAG is set to .TRUE., the
procedure will only print out the SW-NE diagonal of the native grid.
