HPC QPF through 72 hours and HPC Medium Range (Days three
through 7) Max/Min/PoP data are available on IFPS/GFE.
Click POPULATE then Copy All Grids From..
(under the list of sources you should see and select HPCSTN & QPF)
An alternate method is to click Weather Element and then
Weather Element Browser. You should then see HPCSTN and QPF
under SOURCE.
If you do NOT see these available, notify your IFPS focal point
as some local configuration is required to have these visible
in the drop down menus of the grid editor.
NOTE: QPF data is displayed 6 hours off of its valid time!
This is a SOFTWARE glitch that will be corrected by MDL
in IFPS 14.0 (available in May 2003). However, if you'd like a
temporary correction, please see the following instructions:
To shift HPC's QPF back 6 hours...
- Choose from the Menu Bar: GFE --> Define Procedures (A Pop-Up Menu will appear).
- From the Menu Bar: Choose File --> New Item in Window --> Procedures.
A pop-up window appears. Name the procedure shiftQPF and click OK).
- A text editor appears. Write the procedure as follows.
MenuItems = ["Populate"]
import SmartScript
class Procedure (SmartScript.SmartScript):
def __init__ (self,dbss):
SmartScript.SmartScript.__init__ (self,dbss)
def execute (self):
databaseID = self.findDatabase("QPF")
timeRange=self.createTimeRange(0,72,"Database",databaseID)
self.timeShiftCmd(["QPF"], 1, -6, timeRange)
NOTE: Make sure to keep the indentation intact.
Save the procedure to the text editor. The Procedure name will appear in the Populate menu in the
GFE menu bar.
Click on shiftQPF to utilize the procedure.
WARNING: Make sure to only use it ONCE after you have populated your Fcst database with HPCQPF.
Also, when you load HPCSTN data, although 10 possible fields
will load, only 3 are populated so far by HPC (Max/Min/PoP).
The remaining 10 fields in HPCSTN data (sky, wx, wind, etc are
not yet available but will be as the year 2003 progresses).
If you load the HPCSTN Max or Min or PoP data but see empty grids,
you may have to upgrade to IFPS 13.0 or have your IFPS
focal point issue a trouble ticket to NCF.
FYI: HPC will be testing different methods to produce its output optimally for CWAS
with complex terrain. Two methods that will be tested include application of
Mountain Mapper and the SERP tool to HPC Medium Range Forecasts and QPF data.
Output graphics using these methods will posted on this web page as soon as
they are available.
For further information e-mail HPC SOO Pete Manousos or call
him at (301) 763-8000 x 7307.
