| Name | Type | Usage |
|---|---|---|
| VGRIB | INTEGER | Input vorticity field (spectral, GRIB format) |
| DGRIB | INTEGER | Input divergence field (spectral, GRIB format) |
| INLEN | INTEGER | Input field length (words) |
| UGRIB | INTEGER | Output U field (GRIB format) |
| VGRIB | INTEGER | Output V field (GRIB format) |
| OUTLEN | INTEGER | Output field length (words) |
OUTLEN must be provided on input to INTUVP giving the length of the arrays UGRIB and VGRIB. It is returned with the size of the output GRIB in words.
