13 | c Compute the Parameters of the SSO scheme as described in |
---|
14 | c LOTT & MILLER (1997) and LOTT(1999). |
---|
15 | c Target points are on a rectangular grid: |
---|
16 | c iim+1 latitudes including North and South Poles; |
---|
17 | c jjm+1 longitudes, with periodicity jjm+1=1. |
---|
18 | c aux poles. At the poles the fields value is repeated |
---|
19 | c jjm+1 time. |
---|
20 | c The parameters a,b,c,d represent the limite of the target |
---|
21 | c gridpoint region. The means over this region are calculated |
---|
22 | c from USN data, ponderated by a weight proportional to the |
---|
23 | c surface occupated by the data inside the model gridpoint area. |
---|
24 | c In most circumstances, this weight is the ratio between the |
---|
25 | c surface of the USN gridpoint area and the surface of the |
---|
26 | c model gridpoint area. |
