SNEDIT adds data in a sequential edit file to a sounding file. INPUT PARAMETERS SNEFIL *Sounding edit file SNFILE *Sounding data file TIMSTN *Times/additional stations PROGRAM DESCRIPTION SNEDIT adds information from a sequential file to a GEMPAK sounding file. It can be used to add or replace data at a station. The program can be used to add data to either merged or unmerged data sets. The data to be added must be in a text file, SNEFIL. This file can be created using F as the output device in SNLIST. MRGDAT, which can be set in SNLIST, is a flag indicating whether the data to be written will be merged or written as separate parts. If the edit file contains unmerged data, the part name must be included and the parameters must be in the order expected by GEMPAK. If SNFILE exists, the data will be added to the file. If it does not already exist, a new file will be created. A new file will be a merged or unmerged data set, depending on the type of data in SNEFIL. The maximum number of stations and times allocated in a new file will be read from TIMSTN. For merged edit data files, the parameters to be edited must be specified at the beginning of the edit file. For example: PARM=PRES;TMPC;DWPC;DRCT;SPED;HGHT The parameter line must contain the string, PARM, and =. Note that the output of SNLIST is SNPARM = xxxx;yyyy;..., which is valid. If the parameter list must be continued on the next line, the last character on the current line must be a semicolon. If SNFILE is an existing file, the parameters listed in the edit file must be exactly those in the data set. For unmerged data, information about the parameters is not necessary. The information to be added to the sounding file consists of a series of station entries including information for the station, followed by station data,Station information must be listed as KEYWORD = value, where the valid keywords are STID, STNM, SLAT, SLON, SELV, and TIME. The TIME keyword must be found for each station. Either STID or STNM is also required. If the station is not already in the file, the station identifier, station number, latitude, longitude, and elevation found will be added to the file. If the station is already in the file, the station location and elevation will not be changed. Note that program SNSTNS can be used to modify station header values. EXAMPLES 1. Add the data in the edit file, SNLIST.FIL, to the file, SOUND.DAT, which does not exist. SNEFIL = snlist.fil SNOUTF = sound.dat TIMSTN = 1/ 10 The file SNLIST.FIL follows: SNPARM = PRES;TMPC;DWPT;DRCT;SPED;HGHT STNPRM = SHOW;LIFT;KINX STID = IAD STNM = 72403 TIME = 841227/1200 SLAT = 38.98 SLON = -77.46 SELV = 85.0 SHOW = 14.11 LIFT = 25.60 KINX = 11.50 PRES TMPC DWPT DRCT SPED HGHT 1024.00 2.40 -1.40 0.00 0.00 85.00 1000.00 2.20 -3.80 -9999. -9999. 277.00 850.00 5.60 -9.40 -9999. -9999. 1592.00 700.00 -1.90 -2.30 -9999. -9999. 3167.00 500.00 -15.70 -22.70 -9999. -9999. 5790.00 400.00 -28.90 -33.40 -9999. -9999. 7430.00 300.00 -44.30 -93.30 -9999. -9999. 9420.00 250.00 -55.30 -104.3 -9999. -9999. 10620.00 200.00 -66.50 -115.5 -9999. -9999. 12000.00 150.00 -65.90 -114.9 -9999. -9999. 13750.00 100.00 -66.90 -115.9 -9999. -9999. 16220.00 The merged file SOUND.DAT will be created. It will contain the parameters PRES;TMPC;DWPT;DRCT;SPED;HGHT. Space for a maximum of 1 time and 10 stations will be allocated. The time 841227/1200 and station IAD will be added to the file and then the data for that time and station will be added. Note that the stability indices will be ignored. 2. Add the data in the edit file, IAD.FIL, to the unmerged file, REALTIME.SND, which already exists. SNEFIL = realtime.snd SNOUTF = iad.fil TIMSTN = 0 The file IAD.FIL follows: STID = IAD STNM = 72403 TIME = 900823/0000 SLAT = 38.98 SLON = -77.46 SELV = 85.0 TTAA 0 PRES TMPC DWPC DRCT SPED HGHT 1008.00 19.20 18.90 0.00 3.00 -9999.00 1000.00 19.00 18.20 -9999. -9999. 150.00 850.00 14.40 13.30 160.00 8.00 1538.00 700.00 5.40 4.30 240.00 6.00 3157.00 500.00 -8.10 -9.80 215.00 7.00 5850.00 400.00 -19.90 -49.90 225.00 11.00 7540.00 300.00 -34.10 -64.10 235.00 18.00 9620.00 250.00 -44.30 -9999. 245.00 16.00 10870.00 200.00 -54.30 -9999. 250.00 22.00 12330.00 150.00 -60.50 -9999. 265.00 14.00 14140.00 100.00 -64.50 -9999. 235.00 2.00 16620.00 TTBB 0 PRES TMPC DWPC 1008.00 19.20 18.90 850.00 14.40 13.30 684.00 3.60 1.20 602.00 0.00 -1.30 481.00 -9.90 -12.50 PPBB 0 HGHT DRCT SPED 0.00 0.00 3.00 914.00 120.00 12.00 1219.00 130.00 10.00 1829.00 180.00 7.00 2134.00 195.00 6.00 2438.00 210.00 6.00 REMOVE THIS LINE ERROR MESSAGES [SNEDIT +1] Data for ... has been added to the file.
