wxloop.cgi Loop Web-accessible [jpg gif png tiff] files.
Choose images by dates or number of images.
Optimization: For speedy looping, set your browser's memory cache
to 10 MB or more (20 MB recommended for weather discussions) and set
your disk cache to 30-50 MB.
Usage: wxloop.cgi?directory_key+files_to_loop
where:
directory_key --> can take two forms
1) master_path_file_entry
--> any path variable from the master path file,
include_files/master_path_file that
has [jpg gif png tiff] images in the associated directory.
Click here to see a list of possible choices.
Also, see the examples below.
2)fulldir --> full path to an Atm. Sci. directory (starts with /home)
that is Web accessible.
NOTE: If fulldir contains
/home/disk/*/username/public_html/$more then localURL
automatically becomes /~username/$more and these can be
looped over the Web.
ALSO: All [jpg gif png tiff] images in fulldir must be the
same dimension.
2.1)-url localURL --> If fulldir is not of the form /home/disk/*/username/public_html,
then you must specify this. local_URL is path starting with /
that would come after http://www.atmos.washington.edu
files_to_loop --> can take several forms
Please study Examples below to understand this option.
1.1) num --> num is number of most recent images to display
all --> display all images, can be more than 100
today --> display all images since midnight LST
NOTE: No ending slash /
1.2) -n number --> same as 1.1
2.1) timespec --> end/[duration/timestep] -- NOT FOR FORECAST DATA
NOTE: Requires at least one slash /
end --> [yyyymmdd]hh[:nn][p] (specify any unique UTC,
or, if p is used at end, Pacific Local Time Zone,
time closest to the current, e.g. 12 would be 12Z
today if later than 12Z or 12Z yesterday if earlier,
102304 would 4Z Oct 23 of this year or previous
year whichever has most recently occurred,
04:30 would be 04:30Z of most recent occurrence)
DEFAULT is now if left blank.
If not blank, hh is REQUIRED.
duration --> in hours
OVERRIDES: N[dhms] N [days, hours, minutes, seconds]
DEFAULT is 4 hours if left blank.
timestep --> in hours
OVERRIDES: N[dhms] N [days, hours, minutes, seconds]
DEFAULT varies with image type to give all images.
2.2) timespec --> initialization/start/end/timestep -- ONLY FOR FORECAST DATA
Requires at least three slashes ///
initialization
--> [yyyymmdd]hh[:nn] (specify any unique UTC
time closest to the current, e.g. 12 would be 12Z
today if later than 12Z or 12Z yesterday if earlier,
102304 would 4Z Oct 23 of this year or previous
year whichever has most recently occurred,
04:30 would be 04:30Z of most recent occurrence)
DEFAULT is now if left blank.
If not blank, hh is REQUIRED.
start --> in hours, DEFAULT is 0.
end --> in hours, DEFAULT is end of model run (as appropriate).
timestep --> in hours, DEFAULT is 1.
options:
-h(elp) --> print this help message
-pat timepattern --> file times follow the given timepattern where:
YYYY = year
MM = month
DD = day of month
HH = hour (use H3,H6,H9,H12,H18,H24 to match nearest
3,6,9,12,18,24-hour time
NN = minute
SS = second
JJJ = day of year 1 to 366
-v(ersion) --> print the version number of this program
-update nsec or
-ui nsec --> update the loop every nsec seconds
-noauto --> disable auto-update feature.

Problems:
o The Browser's Back Button Does Not Work
Resolution: Some browsers don't interact well with frames. Use my back

o Images Disapper when Loop Stops
Resolution: In some versions of Internet Explorer, you need to click
on the Tools --> Internet Options --> General (a tab) -->
Tempororay Internet files -> Settings (a button) and change it
to "Check for newer versions of stored pages"
"Automatically" or "Never"
o Looping is Slow
Resolution: see Optimizations above
