(Resent. when I haven't seen the original one from the ncl mail list. Sorry for any possible duplication.)

Dear NCL users,
Now, I 'm using the tigge grib2 data as described at http://www.ncl.ucar.edu/Applications/Prints/tigge_ncl_filedump.txt.

I have 3 questions:
1). what is ,say, the q_P0_L100_GGA0 , when q_P1_L100_GGA0 is for the 51 member.

2), in the 51 member fields( like q_p1_l100_gGA0), there is one control run and 50 perturbed run.
How can I know which member is corresponding to the control run.
 3) for on the system I 'm working on is the older ncl with 2GB barrier,
that will be great if there are any ready-to-use script to split that kind of data.
Your help is appreciated.
Best,
Ting
