NWS NCEP REANALYSIS DATA
(DISPLAY
BY NCEP WPC)
This
page displays NCEP Reanalysis Data for user selectable dates.
As
of 04/2008 the archive runs from 00Z Jan. 1, 1948 through 12Z Dec. 31,
2007.
The
images are displayed in four panel format as follows:
-
UPPER
LEFT - 200 mb Heights (contours) and Isotachs in kts (shaded)
-
UPPER
RIGHT - 500 mb Heights (contours) and *Standarized Anomaly (normalized standard deviation) of
500 mb heights (shaded)
-
LOWER
LEFT - 850 mb Heights (white contours), 850 mb Temps (deg C - colored contours),
and *Standardized Anomaly (normalized standard deviation) of 850 mb temperatures (shaded)
-
LOWER
RIGHT - 1000 mb Heights, Precipitable Water (inches), and Standardized Anomaly (normalized standard deviation) of Precipitable Water
* Standarized Anomalies (normalized
Standard Deviation) derived from the archive of 1948-2007.
See
http://www.hpc.ncep.noaa.gov/training/
for background on standard deviations.
The
following information corresponds to the selections available on the right
hand menu.
CURRENT
DATE: Enter the 4 digit year, two digit
month, two digit day, and two digit cycle to display that date's image.
END
DATE: Same as the current date, but
represents the end date of a loop.
BUTTONS:
-
The +/-
buttons over the cycle and day fields will increment/decrement the field
by a value of one AND automatically display the image
-
LOOP will
generate a loop using the current date as the start date and ending with
the end date. A maximum of 62 images are allowed in a loop.
IMAGE
DIRECTORY: Allows you to access the
images you wish on line. Linux users can use the GET command
in a script to automatically grab images they choose. (eg. -
GET http://www.gifs.gov/their.gif > /myPath/my.gif )
END
DATE: Same as the current date, but
represents the end date of a loop.

Thanks
to Rich Grumm (WFO CTP SOO), Mike Bodner (NCEP WPC DTB Met), and Dan Cobb
(former WFO CAR SOO) for assistance with this page. They will shrug and
ask how they assisted, but without Rich's inspiration on Standard Deviations,
and Mike's effort to put together the images and especially the training
link, and even Dan Cobb's assistance with the Linux GET command - this
page would not exist.
