RUC data 18H?

Post by jmagyar » Wed Apr 14, 2010 4:58 pm

When do you think that you might get a chance to possibly update the RUC model to go out to the full 18 hours?

http://www.nws.noaa.gov/om/notification ... hanges.txt

EFFECTIVE TUESDAY MARCH 2 2010...BEGINNING WITH THE 1500
COORDINATED UNIVERSAL TIME /UTC/ RUN...THE NATIONAL CENTERS
FOR ENVIRONMENTAL PREDICTION /NCEP/ WILL UPGRADE THE RAPID
UPDATE CYCLE /RUC/ MODELING SYSTEM.

THE PRIMARY CHANGE IS TO EXTEND THE OUTPUT FROM THE SYSTEM FOR
ALL CYCLES TO 18 HOURS. CURRENTLY THE 00...03...06...09...12...
15...18 AND 21 UTC MODEL CYCLES PRODUCE FORECAST GUIDANCE OUT TO
12 HOURS WITH THE OTHER CYCLES PREDICTING ONLY TO 9 HOURS. WITH
THIS CHANGE ALL GRIB AND BUFR PRODUCTS WILL BE AVAILABLE HOURLY
OUT THROUGH 18 HOURS FOR ALL 24 CYCLES.

There are a couple other priority items right now, but we will add this to the to-do list.

Thought I would bump this up just to see if its still on the TODO list?

You know what, I will bump this again, just cause I want this feature so much :)

But I will put a new request in here as well....Anyway to add the WRF model as well? How about the HRRR? :) Do they put out enough data to work your magic on?

There are many flavors of WRF... NAM is technically WRF-NMM, and there are WRF-ARW East, WRF-ARW West, WRF-NMM East, and WRF-NMM West...there is a flavor of WRF run by NCEP and one by SPC as well. Each one has slightly different physics combinations decided on by whoever is running that model.

For example, we run a WRF-ARW with a specific physics combination that we use for our 'TornadoTarget' product.

HRRR is actually a WRF as well. So yes, we can add some of these, but its not as simple as just adding 'WRF' because WRF is more of a framework for models than it is a model in and of itself. The cores (ARW and NMM) are really the model, and in that regard NAM is what people think of as WRF.

However, WRF-ARW is a much more complex and theoretically better model than WRF-NMM (NAM), but it takes much longer to run and therefore is not as useful as WRF-NMM can be, especially when you want to do an 84 hour forecast.

We could add a high resolution WRF-ARW just to throw in that core to the mix, but it would take some work. What I'd really like to do is redesign the whole F5 package in support for such improvements to do it right.

HRRR, as far as I know, is not something I can add at this time. I haven't seen the data available for that model yet.
