Re: [conduit] information needed about CONDUIT use

I would concur that even more levels below say 750mb would be excellent! The good thing about CONDUIT is that I could pare down what I request to a level that is manageable.

Hello all --

There are two additional data sources that could/would prove useful to me:

4.) Real Time Mesoscale Analyses -  I'd have to see what these consist
of (coverage, format, etc.), but they sound like nice potential retrieval verification and(or) boundary condition fields.

8.) Other - The 47-level, 0.5 degree GFS model output currently provided at would be *very* useful to me if it was available via CONDUIT, since it provides 25mb vertical resolution (at least in terms of temperature) from 1000 -> 100mb. Currently I believe the 0.5 degree GFS data available via CONDUIT is at best 26 levels.

Since we're in request mode....  I might as well ask if there could be
even more vertical levels made available beneath 800mb (beyond the 25mb resolution currently available)? Our work should benefit from as much vertical resolution as possible within and just above the boundary layer. And are there any levels available beneath 1000mb? If the answer to either of these questions is yes, but bandwidth is an issue, then I'd vote for not going all the way out to 180 hours, if that would help.

Thank you very much for your time and considerations!

*Please list the products you currently receive and use via CONDUIT:*
(please provide this information via the *Forum*

NCEP would like to propose that the following data streams be considered
for removal since they are lower resolution versions of other CONDUIT
data streams. /*Please provide your input *//* if you are not in favor
of this:*/

  1. 1.0 degree GFS grids out to 180 hours (NCEP currently provides GFS
     0.5 degree datasets to 180 hours)
  2. 40 km NAM CONUS (NCEP offering to provide 12 km, 60 levels, 84 hrs
     at 0,6,12 and 18Z)
  3. 2.5 degree MRF (GFS) out to 168 hours  (NCEP currently provides
     GFS 0.5 degree datasets to 180 hrs)
  4. Replace 20, 40, and 80 km RUC with 13 km RUC (NCEP offering to
     provide the RUC model at 13 km resolution.  Forecast hours are
     hourly through 12 hours at synoptic times, and hourly through 9
     hours at off-synoptic time)

The following are items that could be distributed via CONDUIT if there
is interest.  Please look these over and indicate which, if any, you
would likely choose to receive if they were made available:

  1. Climate Forecast System products
  2. Short Range Ensemble Forecast data
  3. High Resolution Windows WRF runs (both dynamic cores)
  4. Real Time Mesoscale Analyses
  5. Hurricane Runs (HWRF/GFDL)
  6. Full Domain NAM
  7. Experimental (parallel) runs of NCEP operational models
  8. Other (please specify)
