Convert data from HDF5 to BMP or Netcdf

[oki36]

Hi everyone!
I am currrently doing a research studying storms. I need to use radar data for this. The data is in HDF5, so i have to convert it to BMP or netcdf, i am new in using python and this library "Py-art" . Does anyone can help me with an example script?

Hello! So depending on which format in HDF5 it is in, sinarme, odim etc, you'll use one of the aux io readers. Example:

radar = pyart.aux_io.read_odim_h5('filename')

# output to netCDF
pyart.io.write_cfradial('output_filename', radar, format='NETCDF4')

Thank yoy very much! The data is in HDF5 gamic.
So, i can still write my script like that right?

Also, is the same if i use wradlib?

Yes, but you would have to use the Py-ART gamic reader:

radar = pyart.aux_io.read_gamic('filename')

I'd say it is not the same as using wradlib, as you get back numpy arrays and metadata or xarray Datasets from wradlib. There might be a bit more involved to convert to netcdf as with Py-ART radar-object where you have "batteries" included.

Just a heads up, we (openradar) have a new discourse discussion platform (https://openradar.discourse.group/) for any kind of questions related to weather radar.

You might also want to follow the developments of https://github.com/openradar/xradar, a new radar reader/writer based on xarray/xarray-datatree.

Thank you very much! I'll try using it.
and also I'll follow those platforms.. Thank you.
