1 | make_sso |
---|
2 | |
---|
3 | routine to compute subfgrid scale orography parameters |
---|
4 | from a spherical harmonics method |
---|
5 | |
---|
6 | Requirements: |
---|
7 | - SPHEREPACK library |
---|
8 | - FFTW ? |
---|
9 | - ifortran |
---|
10 | - netcdf |
---|
11 | - an adequate environment defined in make_sso.env |
---|
12 | |
---|
13 | Options: |
---|
14 | |
---|
15 | ./make_sso -i <file> -v <var> -res <nlon> <nlat> -m <mask> -f <ffac> -t |
---|
16 | <tfac> |
---|
17 | |
---|
18 | Where: |
---|
19 | |
---|
20 | <file>: input file name |
---|
21 | <var> : height variable name |
---|
22 | <nlon>: number of distinct longitude points of output grid (iim) |
---|
23 | <nlat>: number of distinct latitude points of output grid (jjm+1) |
---|
24 | <mask>: can be: 1. a mask file (o2a.nc) |
---|
25 | 2. "noro": computed with grid_noro |
---|
26 | default: 3. "spec": computed internally |
---|
27 | <ffac>: filtering width: ffac*Do (Do:output resol.) |
---|
28 | <tfac>: transition width: Di+tfac*(Do-Di) (Di: input resol.) |
---|
29 | |
---|
30 | Note that latitudes grid contains both poles. |
---|
31 | |
---|
32 | |
---|
33 | Example to compile then run make_sso from a high-resolution Relief.nc file to |
---|
34 | a 180x90 horizontal grid. |
---|
35 | |
---|
36 | ./compile |
---|
37 | file=Relief.nc |
---|
38 | ./make_sso -i $file -res 180 91 -v z |
---|
39 | |
---|
40 | Output file is make_sso_180x91_${file} |
---|
