3.3.4 Advection Calculation

The Advection Calculation mode provides access to the advection routine of the SPA. Any level of any field (under the Field Information heading) may be advected by the horizontal wind at any level. The vertical advection calculation is not implemented in version 1.7.1 of this distribution. Although the user may select from either the primary or secondary input data files by pressing the Input Variables button, this usage is discouraged and will likely be disabled in future releases, thus allowing only primary input file entries.
