3.3.8 Sounding

The Sounding mode of MetCal requires NCAR Graphics libraries for plotting. If these libraries were not installed when the SPA was built on your machine, then you will not have access to the sounder. However, if the NCAR Graphics libraries were (and still are) available to MetCal, then the only entries required in the pop-up window are the x,y coordinates of the gridpoint at which to take the sounding (it will be taken at this point for every time in your input file, in keeping with MetCal tradition). The Plot Title entry is one of the few optional entries in the Major Modes. The soundings produced by this algorithm are in “metafiles” produced by NCAR Graphics, and can be viewed with the idt utility distributed with the NCAR Graphics package, accessible through the view output file button on the File IO page (see File io page).
