- CLAMBERT: type of Lambert prjection
- "L1 " : Lambert I
- "L2 " : Lambert II
- "L3 " : Lambert III
- "L4 " : Lambert IV
- "L2E" : Extended Lambert II
- "L93" : Lambert 93
- NPOINTS: number of grid points defining the grid
- XX: X coordinate of grid mesh center
- YY: Y coordinate of grid mesh center
- XDX: grid mesh size on the conformal plane in x direction (real, meters).
- XDY: grid mesh size on the conformal plane in y direction (real, meters).
- XCELLSIZE: size of the cell (equal in X and Y). Has priority on XDX and XDY.
- XX_LLCORNER: X coordinate of left side of the domain.
- XY_LLCORNER: Y coordinate of lower side of the domain.
- NCOLS : number of columns.
- NROWS: number of rows.
The simultaneous use of XX_LLCORNER, XY_LLCORNER, NCOLS and NROWS has priority of this of NPOINTS, XX and YY (it simplifies the namelist in case of a regular grid).
