<br>
I was wondering whether it is possible to replicate the example script<br>
(<a href="https://www.ncl.ucar.edu/Applications/Scripts/gpm_1.ncl" target="_blank">https://www.ncl.ucar.edu/Applications/Scripts/gpm_1.ncl</a>) for GPM<br>
NetCDF data (GIOVANNI offer to generate NetCDF GPM data set). It would<br>
be a great help for people like me, who are more familiar with<br>
manipulating NetCDF data using NCL.<br>
<br>
<br>
Two more subsidiary request:<br>
<br>
1) Is it possible to create the example script that can be executed<br>
using at least NCL 2.6.2 for a wider audience.<br>
<br>
2) Please write the script with a subset of data set instead of global<br>
map (as most of us use this product for RCM validation)<br>
<br>
Here is the link to generate NetCDF GPM data set.<br>
