5 C> This program creates 7 terrain-related files computed from the navy
6 C> 10-minute terrain dataset. The model physics grid parameters and
7 C> spectral truncation and filter parameters are read by this program as
8 C> input.
9 C>
10 C> The 7 files produced are:
11 C> 1. sea-land mask on model physics grid
12 C> 2. gridded orography on model physics grid
13 C> 3. mountain std dev on model physics grid
14 C> 4. spectral orography in spectral domain
15 C> 5. unfiltered gridded orography on model physics grid
16 C> 6. grib sea-land mask on model physics grid
17 C> 7. grib gridded orography on model physics grid
18 C>
19 C> The orography is only filtered for wavenumbers greater than nf0. For
20 C> wavenumbers n between nf0 and nf1, the orography is filtered by the
21 C> factor 1-((n-nf0)/(nf1-nf0))**2. The filtered orography will not have
22 C> information beyond wavenumber nf1.

25 C> - 92-04-16 IREDELL
26 C> - 98-02-02 IREDELL FILTER
27 C> - 98-05-31 HONG Modified for subgrid orography used in Kim's scheme
28 C> - 98-12-31 HONG Modified for high-resolution GTOPO orography
29 C> - 99-05-31 HONG Modified for getting OL4 (mountain fraction)
30 C> - 00-02-10 Moorthi's modifications
31 C> - 00-04-11 HONG Modified for reduced grids
32 C> - 00-04-12 Iredell Modified for reduced grids
33 C> - 02-01-07 (*j*) modified for principal axes of orography
34 C> There are now 14 files, 4 additional for lm mb
35 C> - 04-04-04 (*j*) re-Test on IST/ilen calc for sea-land mask(*j*)
36 C> - 04-09-04 minus sign here in MAKEOA IST and IEN as in MAKEMT!
37 C> - 05-09-05 if test on HK and HLPRIM for GAMMA SQRT
38 C> - 07-08-07 replace 8' with 30" incl GICE, conintue w/ S-Y. lake slm
39 C> - 08-08-07 All input 30", UMD option, and filter as described below
40 C> Quadratic filter applied by default.
41 C> NF0 is normally set to an even value beyond the previous truncation,
42 C> for example, for jcap=382, NF0=254+2
43 C> NF1 is set as jcap+2 (and/or nearest even), eg., for t382, NF1=382+2=384
44 C> if no filter is desired then NF1=NF0=0 and ORF=ORO
45 C> but if no filter but spectral to grid (with gibbs) then NF1=jcap+2, and NF1=jcap+1
