Sometimes a variable may be available as a vertical profile. Sometimes a<br>variable may only be available on<br>one or two levels. When a variable is available as a vertical profile on<br>pressure surfaces, the suffix "prs" is<br>
used. If the variable is not available on a vertical profile, the suffix<br>is the level descriptor.<br><br>Wesley Ebisuzaki<br><br><br>Diego Morelli wrote:<br>><br>> When I use grib2ctl (v0.9.12.5p45) it issues a ctl file with some<br>
