Hi JohnI have gone to the link of 3hourly accumulations of TRMM data. ftp://disc2.nascom.nasa.gov/data/TRMM/Gridded/3B42_V7/201305/and I downloaded the some of the files say, 







3B42.130522.00z.7.precipitation.bin2.2 MB25/07/2013 00:00:003B42.130522.00z.7.relativeError.bin2.2 MB25/07/2013 00:00:003B42.130522.03z.7.precipitation.bin2.2 MB25/07/2013 00:00:003B42.130522.03z.7.relativeError.bin2.2 MB25/07/2013 00:00:003B42.130522.06z.7.precipitation.bin2.2 MB25/07/2013 00:00:003B42.130522.06z.7.relativeError.bin2.2 MB25/07/2013 00:00:003B42.130522.09z.7.precipitation.bin2.2 MB25/07/2013 00:00:003B42.130522.09z.7.relativeError.bin2.2 MB25/07/2013 00:00:003B42.130522.12z.7.precipitation.bin2.2 MB25/07/2013 00:00:003B42.130522.12z.7.relativeError.bin2.2 MB25/07/2013 00:00:003B42.130522.15z.7.precipitation.bin2.2 MB25/07/2013 00:00:003B42.130522.15z.7.relativeError.bin2.2 MB25/07/2013 00:00:003B42.130522.18z.7.precipitation.bin2.2 MB25/07/2013 00:00:003B42.130522.18z.7.relativeError.bin2.2 MB25/07/2013 00:00:003B42.130522.21z.7.precipitation.bin2.2 MB25/07/2013 00:00:003B42.130522.21z.7.relativeError.bin2.2 MB25/07/2013 00:00:003B42.130523.00z.7.precipitati!

I am interested in verifying the model O/P from 0300 of 22-05-2013 to 0300 UTC of 23-05-2013, A total of 8 files.Now how should I combine these binary files into ONE???

Geeta,

Run the trmmbin2nc.R script to convert them to NetCDF.  Then run the
MET
pcp_combine tool to sum up the values.  Optionally, you could run
plot_data_plane to plot the result.

You don't need the relative error binary files, just the precipitation
ones.  Here's an example of commands you could use to process 2 of
these
files.  You could easily put this inside a loop to process all 8 of
them.
I've attached the resulting png image file.

Hope that helps.

Thanks,
John
