SNCFIL creates a new GEMPAK sounding file. INPUT PARAMETERS SNOUTF *Output sounding file SNPRMF *Sounding parameter packing file STNFIL *Station information file MRGDAT *Merge data file flag/part type TIMSTN *Times/additional stations PROGRAM DESCRIPTION SNCFIL creates a GEMPAK sounding file. The file may be created to store merged or unmerged data. Merged data files may contain any meteorological parameters with all parameters included at each level. Unmerged files store the mandatory data and significant-level temperature and wind data as separate parts. MRGDAT must be set to YES or NO. If YES, a merged file will be created. The parameters to be included in the file must be specified in SNPRMF. If MRGDAT is NO, an unmerged file will be created. In this case, the type of unmerged file can be included following a slash. Type 1 creates a file with only mandatory data below 100 mb. Type 2 specifies a file with mandatory and significant-level data below 100 mb, and type 3, which is the default, specifies a file with mandatory and significant-level data below and above 100 mb. SNPRMF contains information about the parameters to be included in a merged file. Either a list of parameters or the name of a packing file may be entered. If a list is entered, the parameters must be separated with semicolons; packing information may also be included after a slash with the minimum and maximum values and the resolution separated using dashes. For example, to include temperature and dewpoint in a file without packing, SNPRMF may be entered as: SNPRMF = TMPC;DWPC To pack the data, use: SNPRMF = TMPC/-127-63-.1;DWPC/-63-63-.1 SNPRMF may also contain the name of a packing file. A packing file for data which is not to be packed contains a list of parameters with one parameter per line. In a file for packed data, each line must include the parameter name, the minimum and maximum data values and the resolution, all separated with spaces. The default packing file for merged sounding data is GEMTABL:SNPACK.TBL. If STNFIL is not blank, information about all the stations in STNFIL will be added to the data set. Space will be left in the file for the additional number of stations specified as the second parameter in TIMSTN. Note that an error will result if STNFIL is blank and TIMSTN does not request additional stations. EXAMPLES 1. Create a sounding file called SOUND.DAT containing merged data. Use the standard station and parameter files. Leave room in the file for 100 stations in addition to the stations in STNFIL and allow 15 times to be added to the file. SNOUTF = sound.dat SNPRMF = gemtabl:snpack.tbl STNFIL = gemtabl:snstns.tbl MRGDAT = yes TIMSTN = 15/100 2. Create an unmerged sounding file called WEEKLY.SND which will store mandatory and significant-level data below and above 100 mb. Do not add any stations now. Leave room for 14 times and 300 stations. SNOUTF = weekly.snd SNPRMF = STNFIL = MRGDAT = no/3 TIMSTN = 14/300 ERROR MESSAGES [SNCFIL +2] Negative number of stations entered -- 0 used. [SNCFIL -1] Fatal error initializing TAE.
