Anybody having idea about extracting and computing cross relation coefficient from polarimetric radar.

Please take a look at the column extract example on the Py-ART gallery  
[https://arm-doe.github.io/pyart/examples/retrieve/plot\_column\_subset.html#sphx-glr-examples-retrieve-plot-column-subset-py](https://arm-doe.github.io/pyart/examples/retrieve/plot_column_subset.html#sphx-glr-examples-retrieve-plot-column-subset-py)

The library example galleries are a great place to start. In terms of computing it, none of the toolkits have a function to easily do this - you will need to implement that within your workflow. As a reminder, this forum is meant to be a place to ask general questions/some support, but we cannot write entire workflows from scratch for users.
