Several days ago I sent you  notes on Joint OSSEs (Observing System 
Simulation Experiments) and Joint OSSE Nature Runs (Proxy true 
atmosphere for OSSE. Previous E-mail attached.)  The Nature run (NR) 
for the Joint OSSE in T511 (13 month long) and T799 (two 5 week long) 
are provided by ECMWF and we will concentrate on OSSE using these 
NRs for next few year.  However, soon or later we have to work on higher 
resolution OSSEs with higher resolution nature run to study data impact in 
mesoscale events.  This will involve regional DAS and possibly involve 
regional NRs.  Since mesoscale OSSE consume large amount of resources, 
we need to work on long term plan.  

We will have a meeting on long term plan for meso scale OSSE on 
November 29 at 10am EST at NOAA/NCEP in Washington DC.    In that 
meeting we will discuss about several candidates for the meso-scale NR.  
We are considering NICAM is one of the most strong candidate for the 
meso-scale NR.   I  hope I will be able to provide some progress in 
NICAM.  I found web site
http://www.ccsr.u-tokyo.ac.jp/~satoh/nicam/index.html  
However, there seems to be more material in member only web pages.   I 
hope you will be able to provide more information about progress in 
NICAM.

A few questions I have are:

I think all movies on web sites are from 7km model.  Is this 
correct?  

When I met Dr.Matsuno in January 2006, he mentioned 3.5km 
NICAM model will became unstable after 3 month integration. I 
wonder how long 3.5 km NICAM model runs these days.

I have heard spectral of NICAM showed 3D turbulence 
characteristics.  Do you have any diagram to present spectral 
characteristics of the NICAM?

If you could provide any materials I can distribute to participants, I would 
be very grateful.  I am expecting Steve Lord, Fezhong Weng, Tom 
Schlatter (ESRL), Hans Huang of NCAR, Ron Errico,  Lars Peter 
Riishojgaard, Erik Andersson (ECMWF), Valentine Anantharaj (MSS) 
and other members Joint OSSE team.  I expect, Boulder and EC will join 
through telecom.

I posted a presentation about simulation of GOESR data  by Fuzhong 
Weng, a draft presentation by Steve Lord to NOAA and some note on 
meso scale OSSE at.

Any information appreciated.
Thank you very much.
