Adding netcdf files....

Hello Ncl Users,

I am working with an hourly database of netcdf files. The data is a
snapshot of sea surface currents. So it has [time Lat Lon] Every hour
of sea-surface currents u and v. I have monthly data which in total
are 743 netcdf files. I am running the NCL opendap support and I
understand that it only reads 64 files and that I am trying to add the
743 files into one single variable call Month. I was able to add the
743 files by following one of the ncl-talk archives that I can set the
following setfileoption("nc","SuppressClose",False)

Now that I have it on one single variable call Month. I am trying to
grab for each hour the u and v o on each one and retrieve the u and v
to make calculations and to put it on a new file. I was trying to
retrieve each u and v for all the times but the error that I was
getting said
warning:FileReadVar: time contains a 0 length dimension
fatal:Subscript out of range, error in subscript #0
fatal:Memory allocation failure:[errno=12]
fatal:Execute: Error occurred at or near line 37 in file addfiles_2.ncl

I notice a memory allocation and decided to retrieve less files no
problem retrieving 51 files. This is the result
Variable: v
Type: float
Total Size: 3659760 bytes
            914940 values
Number of Dimensions: 3
Dimensions and sizes: [time | 51] x [lat | 130] x [lon | 138]
Coordinates:
            time: [2922..2924.083333333372]
            lat: [35.0052..41.96346]
            lon: [-75.9895..-68.0332]

This is my following script

flista=systemfunc("ls " + codDir + "OI_MARC_2009_01_*_*.nc");
print(flista);
month=addfiles(flista,"r");
print(month);
ListSetType(month, "cat") ; default

do i=0,743
u=month[:]->u(i,:,:);
v=month[:]->v(i,:,:)
end do
printVarSummary(u);
printVarSummary(v);

My goal is to put the 743 files on to one single netcdf file. So that
I can use it to calculate monthly means, coverages. Is this possible
or should I just create files in sections and then concatenate to have
the entire month. In the end I would also like to have my hourly data
of netcdf files every three months to calculate seasonal statistics as
well. Any ideas suggestions are welcome and really appreciate it.
