| symbol | Fortran | C |
| proj | CHARACTER(4) | char [4] |
| gridsize | INTEGER, DIMENSION(2) | N_SI4 [2] |
| geometry | REAL, DIMENSION(2, 7) | float [7][2] |
| tattr | CHARACTER(4) | char [4] |
| io | (should be symbol/macro defined in header file) | |
| iostat | INTEGER, INTENT(OUT) | (not used) |
projfour-character symbol of projection type. The name is different from that in type1 string, the corresponding values are following table.
| Projection | type1 string | proj parameter | remarks |
|---|---|---|---|
| CylindricalEquid | "LL" | "LL " | . |
| LambertConformal | "LM" | "LMN " | Northern hemisphere (*) |
| "LMS " | Southern hemisphere | ||
| PolarStereo | "PS" | "PSN " | Northern hemisphere |
| "PSS " | Southern hemisphere | ||
| Mercator | "MR" | "MER " | . |
| Gaussian grid | "GS" | "GS " | . |
| ObliqueLambert | "OL" | "OL " | Specified for RADAR data of Japan area. Some parameters are due to the agreement between the users. |
| Section of latitude | "XP" | "XP " | . |
| Section of longitude | "YP" | "YP " | . |
| "Free Grid" | "FG" | "FG " | . |
| RADAR site | "RD" | "RD " | Peculiar to each site |
| Station data | "ST" | "ST " | . |
(*) In case of LambertConformal or PolarStereo, the "N" or "S" character is added to the proj parameter. The character is decided with the location of the basepoint, indicated in the definition file. The equator is equated to northern hemisphere.
gridsizegrid size.
geometrybyte offset 80--135 in CNTL record.
tattrfour-character symbol which denotes how grid point value represents physical field with regard to spatial dimensions. Note that it is different from symbols in type2 string. See "value" statement in Definition File Format for possible values.
ioone of following symbols
writes SUBC record.
reads SUBC record.
