| uvcalcll.f | This Fortran program will compute geostrophic winds from the height field of a latitude-longitude grid. |
| uvcalcp.f | This Fortran program will compute geostrophic winds from the height field of a polar-stereographic grid. |
| uvrot.f | This Fortran program rotates winds, which were originally given relative to a polar-stereographic grid, to a true N-S/E-W sense. The output values assume that the data are now on a latitude-longitude grid. |
| uvrotp.f | This Fortran program rotates winds, which were originally given relative to a polar-stereographic grid, to a true N-S/E-W sense. The output values assume that the data are still on a polar-stereographic grid. |
