c * This package provides input routines to read the wind *
|
|
|
3 |
c * and other fields from IVE necdf files. The routines are *
|
|
|
4 |
c * *
|
|
|
5 |
c * 1) input_open : to open a data file *
|
|
|
6 |
c * 2) input_grid : to read the grid information, including *
|
|
|
7 |
c * the vertical levels *
|
|
|
8 |
c * 3) input_wind : to read the wind components *
|
|
|
9 |
c * 4) input_close : to close an input file *
|
|
|
10 |
c * *
|
|
|
11 |
c * The file is characterised by an filename <filename> and *
|
|
|
12 |
c * a file identifier <fid>. The horizontal grid is given by *
|
|
|
13 |
c * <xmin,xmax,ymin,ymax,dx,dy,nx,ny> where the pole of the *
|
|
|
14 |
c * rotated grid is given by <pollon,pollat>. The vertical *
|
|
|
15 |
c * grid is characterised by the surface pressure <ps> and *
|
|
|
16 |
c * the pressure at staggered <slev> and unstaggered <ulev> *
|
|
|
17 |
c * levels. The number of levels is given by <nz>. Finally, *
|
|
|
18 |
c * the retrieval of the wind <field> with name <fieldname> *
|
|
|
19 |
c * is characterised by a <time> and a missing data value *
|
|
|
20 |
c * <mdv>. *
