20050304: Storm Report Problems
- Subject: 20050304: Storm Report Problems
- Date: 04 Mar 2005 14:06:57 -0700
Robert,
The NWUS2[02] files have report times in minutes. If you are
plotting a single time from the files created by dcstorm, you would
only see the reports at the time you specify, that could be 1, or dozens
of reports depending on the data file. If you specify a time range, each
frame would have the reports for the valid time. If you are overlaying
radar images in NMAP2, then the storm report time closest to the image
would be used when the dominant time is the image time.
Using SFLIST with SFFILE=SELS will show all the available report times,
for instance yesterday:
SFFILE = sels|050303/0000
AREA = uslcc
DATTIM = all
SFPARM = dset
OUTPUT = t
IDNTYP = stid
GEMPAK-SFLIST>r
PARM =
EVNT;STAT;DATE;HOUR
STN YYMMDD/HHMM EVNT STAT DATE HOUR

If you wanted to bin these to a single date/time, you could
use sfcfil to create a new file, and sfmod to re-assign those
times with DATOUT, eg:
% sfcfil
SFOUTF Output surface file newsels.gem
SFPRMF Surface parameter packing file sels.pack
STNFIL Station information file
SHIPFL Ship data file flag no
TIMSTN Times/additional stations 24/20000
SFFSRC Surface file source
Parameters requested: SFOUTF,SFPRMF,STNFIL,SHIPFL,TIMSTN,SFFSRC.
GEMPAK-SFCFIL>r
SFCFIL PARAMETERS:
New surface file:
newsels.gem
Parameter file:
sels.pack
Station
file:
Number of stations in STNFIL: 0
Number of additional stations: 20000
Total number of stations: 20000
Total number of times: 24
This file will be a standard surface file.

Note, you could bin hourly, daily, 15 minutes, etc.
As I binned yesterday's reports as a single time, I can plot
those obs with in sfmap such as:
GEMPAK-SFMAP>l
AREA = dset
GAREA = uslcc
SATFIL =
RADFIL =
IMCBAR =
SFPARM = mark:3
DATTIM = all
SFFILE = newsels.gem
COLORS = 2
MAP = 31/1/2
MSCALE =
LATLON = 0
TITLE = 5/-1
CLEAR = y
PANEL = 0
DEVICE = xw
PROJ = def
FILTER = n
TEXT = 1/21//hw
LUTFIL = default
STNPLT =
CLRBAR = 1
GEMPAK-SFMAP>r
SFMAP PARAMETERS:

The redbook product is that created by SPC. The legend in the product
gives the count of reports, and is reporting zero at this time. The
rendering of this product is just what is in the graphics drawing
commands of the rebook.
