- Wind on a separate curvi-linear grid:
- Explanation of the data to grid conversion for Pseudo ArcInfo wind
For Pseudo ArcInfo wind the orientation of the data is the same as the grid (visually). The first data value is thus located at the grid at (1,nmax). A line is then read as a row on the grid and the 2nd line in the dataset is row nmax-1 on the grid. See also figure 1.

- Spiderweb wind:
- Explanation of the data to grid conversion for wind on a separate curvi-linear grid.
The first_data_value keyword is used to determine the starting point on the grid. The first_data_value is the first value that is read in the meteo file, i.e. the upper left value in a datablock. The keyword has 4 possible values:
grid_llcorner, meaning m = 1, n = 1 (on the curvilinear grid)
grid_lrcorner, meaning m = mmax, n = 1 ( " )
grid_ulcorner, meaning m = 1, n = nmax ( " )
grid_urcorner, meaning m = mmax, n = nmax ( " )
The data_row keyword is then used to determine the direction of placing the data on the grid, i.e. data_row = grid_column means that a row that is read in the meteo file becomes a column in the array on the grid (so fixed m, increasing n).
Example:
| Code Block |
|---|
first_data_value = grid_ll_corner
data_row = grid_column
|
means:
The first read value (top left) of the meteofile coincides with the point (1,1) on the grid. The first row in the meteofile is then the first column on the grid, i.e. (1,1:nmax). The second row is then the second column (2,1:nmax) and so on. See also Figure 2.
