Dear IMD Radar data users,

I want to draw your attention to the fact that I've created a Python library, PyScanCf, for Indian Meteorological Department Weather Radar data. They provide about ten single scans for the entire volume of the atmosphere over a particular domain in FSL NetCDF format.
PyScanCf was developed to convert this data to Cf-radial, gridded, and plot Cappi. It has been designed to make the output data compatible with Pyart and Wradlib, allowing users to perform additional processing.
The library was created out of necessity and was inspired by open-source libraries such as Pyart and Wradlib.
Please keep in mind that it uses Pyart to convert data to a gridded format.

Thanks and regards,
Syed Hamid

Hi, this is nice! I have always wanted to plot IMD radar data, but is the data available to the public (and in real time)? Thank you.

But using PyScanCf, some of the important radar parameters get lost. I just used it and ZdR, KdP, RHOHV were not there in the new created file.

Hi Mohit, 
The reason is that most of the IMD radars operate on single polarization. They have only a few radars that are operating on Dual-Pol.
Kindly raise an issue here at https://github.com/syedhamidali/PyScanCf/issues, and if possible, share some data files so that I may take a look. And for future correspondence, please use the discussions feature here https://github.com/syedhamidali/PyScanCf/discussions.
Best,
Hamid

Hey All!

First congratulations and thanks Hamid on making this package!

https://github.com/syedhamidali/PyScanCf

 

We should get this added to the open radar organization

https://openradarscience.org/

 

Max and Kai can correct me if wrong but I think you put a pull request up against

https://github.com/openradar/openradar.github.io/blob/master/projects/index.html

Hi Scott, Hamid,

The openradarscience landing page source code is at

https://github.com/openradar/openradar-landing-page

Please have a look at the commits there on how to add a package.

Best,
Kai

Hi Dr. Scott, Kai,

Thank you a lot! I'd like to include this in the open radar science projects as soon as possible.
Thank you, Kai, for these instructions as well. You've always been helpful to me since I first joined the radar community.

Best,
Hamid

I have also used IMD New Delhi Radar Natcdf file for plotting  .

If we combine all into one project than it really become very useful for upcoming learners. 

Please make a group for Indian Radar plotation scripts or we all can prepare a single project as per queries will come.
