Sumeet,

depending on the file size of the individual nc files, a number of tools would be appropriate.  The NCO utilities such as ncks or ncrcat could be used at the unix/linux command line to first make a single large nc file (perhaps of a few GB), that you could then convert in matlab to .mat format.

Hi Sumeet, 

If the netcdf files are all in one directory that matlab can look at...

n_files=2000;

file_names=char(ls);

file_names=file_names(3:n_files,:); % removes first two entries which are .'s

for n=1:n_files

function_call ( file_names(n,:) , ..... )

end

What is the size of each individual file? 2D fields?

@arian its a 3D file with Time x Lat x Long.The size is 24x2x2. 

%You can use this loop if the file names are file_name_1.nc, file_name_2.nc, ..., file_name_2000.nc

tata=[];

for ii=1:2000

file=(['C:\file_name_' num2str(ii) '.nc']);

toto=nc_varget(file,'var');

tata=vertcat(tata,toto);

end

%At the end, the size of tata is tata(48000,2,2)

@Adrian:Actually i am having 6 hourly dataset clubbed into 4 days for per file.Total period is 1979-2005(around 1800 files).I have mentioned specimen file names below.Please specify if matlab coding for such files is possible.Thanks in advance

pgbh06.gdas.19790101-19790105.grb2.nc

pgbh06.gdas.19790106-19790110.grb2.nc

pgbh06.gdas.19790111-19790115.grb2.nc

You can create your filenames in this way: 

year = 1979;

month = 1;

day1 = 1;

day2 = 5;

fileName = sprintf('pgbh06.gdas.%i%02i%02i-%i%02i%02i.grb2.nc',year,month,day1,year,month,day2)

fileName =

pgbh06.gdas.19790101-19790105.grb2.nc

@Adrian:The code worked thanks for  timely help and efforts!!

You can extract your data from many nc files by using netcdf-extractor V2.0 in:

http://www.agrimetsoft.com/netcdf-extractor.aspx

It can merge your files and extract your time series from merged files.

It's so simple. Please watch this video:
