Model domain settings
For each domain we set variables related to the geometry and the resolution like:
The following variables related to the geometry and the resolution are required:
| Variable | Description |
|---|---|
TSTEP | model timestep in seconds |
NLON | number of points in x-direction |
NLAT | number of points in y-direction |
LONC | longitude of domain centre in degrees |
LATC | latitude of domain center in degrees |
LON0 | reference longitude of the projection in degrees |
LAT0 | reference latitude of the projection in degrees |
GSIZE | grid size in meters in both x- and y-direction |
EZONE | number of points over extension zone in both x- and y-direction |
LMRT | switch for rotated Mercator projection. If LMRT=.TRUE. LAT0 should be zero |
- If
LAT0 = 90, the projection is polar stereographic. - If
LAT0 < 90, the projection is lambert unlessLMRT=.TRUE.._
NLON and NLAT should satisfy the equation $2^a ⋅ 3^b ⋅ 5^c$, where either $a ≥ 1, b ≥ 0, c ≥ 0$ or $a=b=c=0$
