SNLIST lists upper air data from a sounding file for specified vertical levels and stations. INPUT PARAMETERS SNFILE *Sounding data file AREA *Data area DATTIM *Date/time SNPARM *Sounding parameter list STNDEX *Stability indices LEVELS *Vertical levels VCOORD *Vertical coordinate type OUTPUT *Output device/filename MRGDAT *Merge data file flag/part type PROGRAM DESCRIPTION SNLIST lists parameters derived from an upper air data set for the requested stations and times. Parameters which can be computed at various levels in the data set should be specified in SNPARM. Parameters which have a single value at the station, such as stability indices, should be specified in STNDEX. Any parameters which can be computed from the data set parameters may be listed. If the vertical levels requested are not present in the data set, the data will be interpolated between existing levels. Data will also be interpolated to a new vertical coordinate system, if requested. Data from an unmerged data set can be listed without being merged if MRGDAT is set to NO. If unmerged data are listed, SNPARM, VCOORD and LEVELS will be ignored. EXAMPLES 1. List at the terminal the parameters in the data set for the station IAD at the mandatory levels. Also list the Showalter, lifted and K indices. SNFILE = gemdata:84dec.snd AREA = @iad DATTIM = 27/12 SNPARM = dset STNDEX = show;lift;kinx LEVELS = man VCOORD = pres OUTPUT = t 2. List the pressure, mixing ratio, u- and v-wind components and the Montgomery stream function on the isentropic surfaces from 300 to 400 degrees in 10-degree increments. Change the station to SLO.
